Les cinq participants suisses ont pris part au concours depuis Signau (BE) - et ont remporté une médaille de bronze et trois mentions honorables.
Hundreds of global researchers, including University of Zurich, are planning the most sensitive dark matter detector ever built.
The XENON/DARWIN and LUX-ZEPLIN collaborations have now joined forces to work together on the design, construction, and operation of a new, single, multi-tonne scale xenon observatory to explore dark matter. The detector will be highly sensitive to a wide range of proposed dark matter particles and their interactions with visible matter. Over the last 20+ years, experiments using liquefied xenon targets have delivered world-leading results in the global quest for direct dark matter detection. This next-generation detector aims to continue the pursuit.
Survey about the Swiss Society for Crystallography
La recherche de la matière noire est l'un des "sujets brûlants" actuels de la physique des particules élémentaires. Récemment, de puissants détecteurs ont été mis au point, qui pourraient permettre de détecter expérimentalement les composants de cette matière "noire", invisible. Laura Baudis, professeur de physique à l'université de Zurich, a largement contribué au développement de cette infrastructure de recherche au cours des vingt dernières années.

The newly opened Science Exploratorium of the University of Zurich hosts temporary exhibitions in which researchers share their enthusiasm for their research topics.
The European Research Centre for Particle Physics (CERN) in Geneva is currently working on making the measurement data from four large-scale experiments available to the public via internet. This form of 'open science' benefits particle physicists around the globe, but also students or high school students - for example in Switzerland.
The Trust Science pledge is a worldwide campaign to promote support for the scientific process and to acknowledge the many benefits of science for society.
At the beginning of April, the US research laboratory Fermilab published a new result for the magnetic dipole moment of the muon. The result caused a broad media response because it deviates from the theoretical predictions and thus questions the previous understanding of the laws of nature. Researchers from the Albert Einstein Center for Fundamental Physics (AEC) at the University of Bern were involved in the theoretical predictions. Prof. Martin Hoferichter, theoretical physicist at the AEC, explains the background.
En Italie, les collégiennes terminant la maturité gymnasiale choisissent d'étudier la physique beaucoup plus naturellement que ce n'est actuellement le cas en Suisse. Ilaria Zardo fait partie de ces jeunes Italiennes qui se sont d'abord enthousiasmées pour les études de physique, puis pour la recherche universitaire. Aujourd'hui professeure à l'Université de Bâle, elle étudie avec son groupe de recherche les flux thermiques à l'échelle nanométrique.
When people talk about CERN, they inevitably think of the large-scale experiments at the Large Hadron Collider (LHC). But the European Laboratory for Particle Physics has even more to offer: A small but powerful experiment called FASER is currently being assembled at CERN, involving research teams led by Geneva physics professors Anna Sfyrla and Giuseppe Iacobucci and by Bern physics professor Akitaka Ariga. FASER proves: Even comparatively inexpensive experiments have the potential for groundbreaking scientific findings.

Almost ten years ago, the European Laboratory for Particle Physics (CERN) made headlines with the discovery of the Higgs particle. These days, the LHCb experiment at CERN has published results that also have the makings of a real scientific sensation: studies of the so-called beauty quark suggest that there could be a fifth, super-weak force in addition to the four known forces of nature (electromagnetism, gravitation, strong and weak interaction). However, CERN researchers still have a lot of work ahead of them to confirm this spectacular hypothesis. At the forefront: particle physicists from the University of Zurich and EPF Lausanne
Until his retirement in 2017, Martin Pohl was a physics professor at the University of Geneva and worked on particle physics research projects for almost half a century. Drawing on this wealth of experience, a book has been written in which Pohl knowledgeably traces the developmental strands of this fundamental discipline. The culmination is the 'Standard Model' of particle physics - for Pohl a scientific highlight and a burden at the same time.
This community roadmap summarizes a survey of the Swiss large-scale infrastructure requirements in the broad field of photon science for the years 2025–2028, drawing from the current situation both in Switzerland and abroad. The Swiss Society for Photon Science (SSPh) collected the scientific visions and compiled the needs of the community of photon science, which encompasses all research areas that work to generate, manipulate and detect photons or use them to investigate or control complex assemblies of matter.
This community roadmap presents the visions for future research in particle and astroparticle physics in Switzerland and formulates the needs of these fields in terms of research infrastructure in the years 2025-2028 and beyond. It was established under the auspices of the Swiss Institute of Particle Physics (CHIPP), which issued its first roadmap already in 2004 and conducted dedicated roadmap-planning workshops in 2018 and 2020.
This community roadmap presents a broad overview of the current status of neutron science in Switzerland and derives a set of recommendations for future developments.

The technical know-how that physicists use in research could soon serve in the fight against the COVID-19 pandemic. An international team of scientists with strong Swiss participation has developed a ventilator in record time that could help in the future against lung diseases like Corona, especially in countries with a precarious medical infrastructure.
In the laboratories of modern physics the elementary components of matter are studied. To do this, scientists sometimes build artificial atoms to help them understand the laws of matter. A research team at the Paul Scherrer Institute (Villigen/AG) uses a specifically modified helium atom to determine the exact mass and other properties of pions. Pions could help to understand more precisely where atomic nuclei get their mass from.

At the age of 28, the Italian experimental physicist has already made a remarkable journey as a researcher. She is now receiving the PhD prize in Swiss particle physics - among other things for her findings in the context of the most massive of all elementary particles.
Executive summary of an analysis prepared by the Centre for Economics and Business Research (Cebr) for the European Physical Society (EPS)
On June 19th CERN Council adopted the update of the "European Strategy for Particle Physics 2020". This document updates an earlier strategy paper that was adopted by the Council in 2013, just after the Higgs discovery in 2012. It identifies the medium and long-term priorities of fundamental research in particle physics and thus forms an important basis for the construction of the European research infrastructure. The implications of this strategy update for Swiss particle physics are answered by Rainer Wallny, Professor of Particle Physics at ETH Zurich and President of the Swiss Institute of Particle Physics (CHIPP), the umbrella organisation of Swiss particle physics.
The delta+ is a type of baryon, the family of sub-atomic particles to which the more well-known proton and neutron belong. A team of physics enthusiasts at the International School of Geneva is working intensively on these extremely unstable elementary particles. In September they will travel to Hamburg for an experiment at the renowned particle physics research institute DESY. They owe this extraordinary research trip to winning this year's “Beamline for Schools” (BL4S) competition at CERN.

When analyzing data from the XENON1T detector for dark matter, a signal excess was observed. The UZH researchers do not yet know for sure where this unexpected signal comes from. They say the origins could be relatively banal, but they could also indicate the existence of new particles or hitherto unknown properties of neutrinos.
To recognise the International Day of Light 2020 and the 60th anniversary of the laser, the Swiss Physical Society (SPS) publishes a detailed report by René Salathé (EPFL) to record the development and milestones in laser science from 1960 to 1980 in Switzerland.

This media update is part of a series related to the 2020 Large Hadron Collider Physics (LHCP2020) conference, taking place 25–30 May 2020.
Positron emission tomography (PET) helps medical doctors to detect cancer and many other diseases. A team of researchers led by ETH Professor Günther Dissertori is working on a new generation of PET scanners that could in future be of great use in pharmacological research and in the treatment of Alzheimer's patients. The technical innovation is based, among other things, on fundamental research at CERN.
FCC - these three letters stand for the vision of a new ring accelerator that could be built at the European particle physics laboratory CERN in Geneva. With this long-term goal in mind, Swiss physicists founded the CHART research initiative five years ago. Now the demonstrator of a powerful magnet is available. If the tests are successful, a very first step towards decisive progress in infrastructure for basic research, but also in applications such as, e.g., innovative instrumentation for medical therapies will be achieved.
Une équipe scientifique internationale a réussi à détecter une manifestation de la brisure de la symétrie fondamentale de la nature qui a permis à la matière de dominer l’Univers au détriment de l’antimatière.
Scientists at the University of Applied Sciences and Arts Northwestern Switzerland (FHNW) have spent around ten years building the Spectrometer / Telescope for Imaging X-rays (STIX). Since 10 February, the research instrument is travelling to the Sun. It will provide accurate measurements of the solar atmosphere and the solar wind and will also cover the polar regions of the Sun that cannot be observed from Earth.
With its European particle physics laboratory CERN, Geneva attracts many researchers to Switzerland. This was also the case with François Drielsma (28). In a doctoral thesis supervised by Prof. Alain Blondel (University of Geneva), the Belgian-born scientist investigated a completely new way to build a particle accelerator.
Particle physicists from all over Europe are currently discussing the future of European particle physics, when the current ring accelerator LHC will be decommissioned around 2035. Next May, the decision could be taken launch technical and financial feasibility studies for the construction of a new, even more powerful particle accelerator.
This week’s drafting session marks final discussions for the update of the European strategy for particle physics
Elementary particle physics and the large-scale CERN research facility have repeatedly inspired artists to engage with modern scientific research. The latest example is the movie 'Les Particules' by French-Swiss filmmaker Blaise Harrison (39). In this art piece scientific research serves as an escape and dream world for an adolescent.
Lesya Shchutska (pronounced: Schutska) is 33 years old and already Professor of Elementary Particle Physics at the Swiss Federal Institute of Technology Lausanne (EPFL). "At the moment I can't imagine doing anything other than physics," says the researcher, who deals with particles that so far only exist in the minds of theoretical physicists.
At the occasion of the Swiss Geoscience meeting in Fribourg in November 2019, the ACP Award for Atmospheric Research was presented to Daniele Nerini for his PhD thesis “Ensemble precipitation nowcasting: limits to prediction, localization and seamless blending”.

In deep underground tunnels of former mines near the Japanese Alps, teams of scientists with Swiss participation are researching various types of elementary particles. Over the next few years, powerful research instruments will be put into operation with which scientists want to discover the nature of neutrinos. The hoped-for results could lead to solving of deep puzzles in our understanding of the universe.
Hardly any elementary particle occurs more frequently in the universe than the elusive neutrino. The investigation of the almost massless tiny particle is a focus of current elementary particle physics. Perhaps the most important contribution to the understanding of neutrino has been made over twenty years by the Japanese Super-Kamiokande detector, in which several Swiss research groups are involved. A visit to the Japanese mountains.
Pickel, Schaufel und Spatel gehören zwar noch immer zur archäologischen Feldausrüstung, immer öfter kommen aber bereits im Feld oder spätestens bei der Auswertung im Büro High-Tech Geräte zum Einsatz. Tragbare Röntgenfluoreszenz-Analysatoren sind ein Beispiel solcher Geräte, die zur grossen Freude archäologischer Konservatoren zerstörungsfreie Analysen ermöglichen.
Graben oder nicht graben? Das ist oft die Frage! Die Entscheidung müssen Archäologen aber nicht dem Zufall überlassen. Geophysikalische Prospektionen und die Fernerkundung erlauben sehr weit gehende Einsichten in den Untergrund, bevor die erste Schaufel Erdreich bewegt wird. Die dadurch gewonnenen digitalen Daten bilden die ideale Grundlage, um einen antiken Fundort durch gezieltes Anlegen von Grabungsschnitten möglichst detailliert zu erkunden.
Wollen Archäologen ohne zu graben den Untergrund erforschen, dann greifen sie zu geophysikalischen Methoden. Bei Luftbildauswertungen und elektrischen Widerstandsmessungen in Studen kam Erstaunliches zu Tage – aber auch die Erkenntnis, dass ein Grossteil des römischen Vicus undokumentiert dem Kiesabbau zum Opfer gefallen ist.
Neutrinos are ubiquitous yet elusive particles that could shed light on the early evolution of the universe. As one of the world’s major laboratories for neutrino physics, Fermilab partners with leading organizations around the globe to get a firmer grasp on these subtle particles.

Radioactive waste from nuclear power plants can take a long time to decay. For plutonium-239 the half-life - that is the time until half of the atoms of a sample have decayed - is no less than 24,000 years. But this is nothing compared to the half-life of the noble gas xenon-124, as an international research team with collaborators from the University of Zurich has now shown.
From 2026, the performance of the large-scale experiments at the European particle physics laboratory, CERN, in Geneva will be significantly increased. The preliminary work for the upgrade of the large particle accelerator LHC and the associated detectors is currently in full swing. An important contribution is made by the University of Bern, where doctoral student Armin Fehr (26) and his colleagues are working on a component for the ATLAS detector. This component will enable the read-out of the greatly increased data rates from 2026 onwards.

Gravity accompanies us in our everyday lives—from early morning, when we get out of bed, to late evening, when we drop tiredly onto the mattress. Although no other force of nature shapes our lives as much as gravity, we still know little about it. Many scientists around the world are working to uncover the secrets of gravity. One of them is researching in Canton Aargau: the 32-year-old particle physicist Anna Soter.
The CHIPP Prize is to reward annually the best PhD student in Experimental or Theoretical Particle Physics. In the evaluation, emphasis will be given to the quality of PhD scientific work and to its relevance within the student's research group, as well as to novel ideas brought up by the candidate.
Le tableau périodique des éléments chimiques est l'une des réalisations les plus importantes de la science, qui rend compte non seulement de l'essence de la chimie, mais aussi de la physique et de la biologie. 1869 est considérée comme l'année de formulation du concept moderne du système périodique par Dmitri Mendeleev (et d'autres). 2019 marque le 150e anniversaire de cette formulation et a donc été proclamée "Année internationale du tableau périodique des éléments chimiques (IYPT2019)" par l'Assemblée générale des Nations Unies et l'UNESCO.
À une époque où beaucoup de pays d'Europe se refermaient sur eux-mêmes, la Suisse ouvrait une station de recherche à vocation internationale au Jungfraujoch. Plusieurs prix Nobel y ont travaillé. En 2019, la station se voit honorée de deux récompenses qui la consacrent Grand site historique des sciences. La Société européenne de physique lui rend honneur dans le domaine des sciences physiques et l'Académie suisse des sciences naturelles dans celui de la chimie.

Etalement urbain, déclin de la diversité des paysages et de la biodiversité, paysages de montagne marqués par le changement climatique: afin de mieux protéger les paysages suisses avec l’implication de la sphère politique et de la société, de les utiliser et de les façonner de manière plus durable, l'Académie des sciences naturelles (SCNAT) regroupe dès 2019 différentes activités dans une entité baptisée Forum Paysage, Alpes et Parcs. Le plus grand réseau de connaissances sur les paysages naturels et culturels en Suisse verra ainsi le jour. Felix Kienast, de l'Institut fédéral de recherches sur la forêt, la neige et le paysage WSL, en est le président. De même, de nouveaux présidents viennent d’être nommés à la tête d'autres unités de la SCNAT.
In spring 2020 the European particle physics community will decide on a new European Strategy highlighting the strategic long-term goals in this important field of fundamental research. In December 2018 Swiss scientists – organized by the Swiss Institute of Particle Physics / CHIPP – have formulated their input to the new European Strategy. Günther Dissertori – professor at ETH Zurich, member of the CHIPP Executive Board and incoming Scientific Delegate of Switzerland in the CERN Council – explains the main points of the Swiss strategic input.
Prof. Ernst Meyer (Uni. Basel) is the new President of the Platform MAP starting in 2019. He succeeds to Prof. Friedrich-Karl Thielemann (Uni. Basel), who served for six years (2013-2018) as President and stays in the Presidium for another three-year term.

In the first workshop in April, the status of the field was reviewed and discussed. The CHIPP input for the discussion of the ESPP update was then agreed during the second workshop held in September. This document describes the CHIPP position on the ESPP update focused on the scientific issues.
APPEC strongly supports and encourages the prospects of an even stronger synergy between Astroparticle Physics and Cosmology with Particle Physics. Areas of synergy between the above domains are identified: dark matter and dark energy; multi-messenger astrophysics, with the recently achieved discoveries of gravitational waves and the extraordinary opportunities also offered by gamma-ray and neutrino observatories for the exploration of powerful accelerators of the universe; the current neutrino precision program in relationship with cosmology, that promise either an unprecedented confirmation of the two standard models of Particle Physics and Cosmology, or a gate to new physics beyond both. These synergies include R&D on photosensors, cryogenic and vacuum techniques, optimisation of large scale infrastructures (civil infrastructure, vacuum, cryogenics) and of their governance and long-term operation, computing strategies for analysis and handling of large volumes of data, and policies leading to open science. Their development also requires grounding fundamental science within society, including, outreach and education. In view of the above synergies the present document introduces and briefly discusses four recommendations related to the role of PP in i) the dark matter searches; ii) the multi-messenger astronomy,in particular the 3G GW experiments (ET); iii) the neutrino physics; iv) the creation of a European Center for AstroParticle Theory (EuCAPT).

Neutrinos are electrically neutral and very light elementary particles, which interact only weakly with other matter and are therefore difficult to observe. From 2025, a new neutrino experiment in the US aims contributing to a better understanding of the neutrinos. At the University of Bern physicists are currently working on the prototype for a detector to be used in the upcoming experiment.
