Image : Jakob Schwander, Universität BernOn 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.
Image : ETHZ, SwitzerlandThe 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.

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.
L'UNESCO célèbre chaque année le 16 mai la Journée internationale de la lumière (IDL en anglais).

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.

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.

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.
IPPOG, the International Particle Physics Outreach Group, is a collaboration comprising 27 signing member-organizations (countries, laboratories, experiments) whose goal is to maximize the impact of education and outreach efforts related to particle physics.
PiA offers 24 entertaining physics experiments to do yourself again this year. Due to the great interest from abroad, physics will be available in English during Advent, just like last year.
Laetitia Laub was born and raised near Lausanne. She studied mathematics and physics at the Federal Institute of Technology in Lausanne (EPFL). Since August 2017, the 24-year-old junior scientist is writing her doctoral thesis in theoretical physics at the University of Bern. In her thesis she deals with the anomalous magnetic dipole moment of the muon and the reaction of this particle in the magnetic field. "Many people are currently working on this theoretical problem with the aim of further reducing the calculation error of the dipol moment. This is also because a better experimental value for the dipole moment will be probably found at Fermilab in the US and J-Parc experiment in Japan soon, " says Laetitia Laub.
Le Prix Nobel de physique 2018 est revenu pour moitié à Arthur Ashkin (USA), ainsi qu'à Gérard Mourou (France) et Donna Strickland (Canada).

Arthur Ashkin a mis au point la pince optique qui permet de manipuler des organismes extrêmement petits comme les cellules, les particules et les virus. Gérard Mourou et Donna Strickland ont inventé la technique d'amplification des lasers, appelé, qui génère des impulsions ultracourtes et de très haute puissance.
At the end of August, climate change and the future energy supply of Switzerland were among the topics of several keynote speeches at the Annual Meeting of the Swiss Physical Society (SPS) and the Swiss Institute of Particle Physics (CHIPP) in Lausanne. Maurice Bourquin, former professor of physics at University of Geneva, gave a keynote lecture about the ongoing transformation of the Swiss energy system. Professor Bourquin was also Rector of the University of Geneva (1999 - 2003) and President of the CERN Council (2001 - 2003). The 77 year-old scientist’s speech was titled: “Thorium-based systems – A new direction for nuclear waste elimination and energy production.” In the interview that follows, Professor Bourquin explains why he still believes in nuclear power.
In order for physicists at CERN to carry out their experiments for the understanding of matter, the large particle accelerator LHC must be operated with the utmost precision. Ensuring this precision both now and in the future was the overriding goal of a doctoral thesis that Claudia Tambasco recently completed at the EPFL in Lausanne. For this work, the young researcher was today (28.08.2018) awarded the prize of the Swiss Institute of Particle Physics (CHIPP) at a ceremony in Lausanne.
Geneva, 28 August. Six years after its discovery, the Higgs boson has at last been observed decaying to fundamental particles known as bottom quarks. The finding, presented today at CERN by the ATLAS and CMS collaborations at the Large Hadron Collider (LHC), is consistent with the hypothesis that the all-pervading quantum field behind the Higgs boson also gives mass to the bottom quark. Both teams have submitted their results for publication today.

In 2021, the European research satellite Euclid will be launched into space. With Euclid, scientists from Switzerland and 15 other countries want to gain a better understanding of dark matter and dark energy. These two 'things' fill large parts of the universe in the view of modern astronomy, but neither dark matter nor dark energy have been directly observed so far. Researchers at the University of Zurich have prepared a complex computer simulation of dark matter in preparation for the Euclid mission. This mission is of great interest not only to astronomers and astrophysicists but also to particle physicists since particle physics is on the quest for the discovery of the nature and structure of dark matter with its own experiments.
If you are looking for unknown things, you usually do not know which way to go to find the unknown. This dilemma is also faced by scientists who want to advance into previously unknown areas of elementary particle physics. And yet they have to find a consensus on which experiments promise the greatest gain in knowledge in the next years and decades. For this purpose, the Swiss particle physicists are currently working on a new research roadmap.
These days, the Swiss-Italian documentary 'CERN and the sense of beauty' will be screened in selected Swiss cinemas. The work of the Italian director Valerio Jalongo combines images from the particle physics research laboratory with nature photographs and with works of art, leading to a subjective and idiosyncratic meditation on knowledge and beauty.
The large particle accelerator LHC at CERN in Geneva enables scientists to get precious clues to understand the nature of matter in the next two decades of data taking. The power and performance of this huge research apparatus needs to be constantly improved for this task. A silicon sensor, which the junior researcher Claudia Merlassino is currently testing at the University of Bern, is planned to be used from 2025 in a large LHC experiment: ATLAS.
CERN in Geneva is the world's largest facility for the study of fundamental particles. The equipment that usually serves science can sometimes be used for practical purposes too. That's for example the case for the protons emerging from the Proton Synchrotron Booster (PSB): they are used in the large particle accelerator LHC for scientific experiments. The protons can also be used to produce isotopes that are useful in radiation medicine. Such isotopes are produced in the recently opened facility CERN-MEDICIS.
On 9 January 2018 the Astroparticle Physics European Consortium (APPEC) will officially launch its new Strategy 2017-2026 in Brussels. The strategy is addressing the main scientific issues of astroparticle physics in the upcoming decade.

Thanks to the University of Geneva Swiss astroparticle physics participates in IceCube - a huge experiment in neutrino research at the South Pole. The scientists aim to probe with IceCube the exact origin of the neutrinos coming from the universe. For over two years the young scientist Tessa Carver (24) has been part of the experiment.
This fall at the Paul Scherrer Institute, the construction of a new particle physics experiment will begin to determine the electric dipole of the neutron. It will replace a previous experiment, which has performed the so far most sensitive measurement in recent years and for which data evaluation is still ongoing. The new experiment, co-developed by ETH Ph.D. student Michał Rawlik, can detect almost inconceivably small features of magnetism. A successful outcome of the experiment would help explain why there is so much more matter in the universe than antimatter.
Researchers of the Baryon-Antibaryon-Symmetry experiment (BASE) at CERN have achieved a remarkable success: They have determined the magnetic moment of the antiproton with a previously unattained accuracy. The measurement is more precise than the best measurement for the magnetic moment of the proton.
La collaboration BASE au CERN publie dans la revue Nature une nouvelle mesure du moment magnétique de l'antiproton, plus précise que celle obtenue pour le proton. C'est probablement la première fois que des physiciens réalisent une mesure plus précise pour l'antimatière que pour la matière, selon les chercheurs.
Trois Américains ont reçu mardi le Nobel de physique pour avoir validé une incroyable prédiction d'Albert Einstein: l'existence d'ondes gravitationnelles créées par les trous noirs. Cette révolution scientifique a propulsé notre connaissance de l'univers jusqu'au coeur du Big Bang.
In 2012, the Higgs particle was detected by the ATLAS and CMS experiments at CERN. Since then, one often hears that the Standard Model of particle physics is complete. "Not quite true!" says Alain Blondel, professor of physics at the University of Geneva. There is still the neutrino, which, as it is known today, does not fit into the Standard Model. Exciting news about the elusive particle was published recently: New observations by the T2K neutrino experiment in Japan provide first indications shedding light to a central question of modern physics: Why does the universe consist only of matter while the associated antimatter is missing?
La semaine des Prix Nobel 2017 commence lundi à Stockholm. Le prix Nobel de médecine ouvrira le bal, suivi, mardi, du Nobel de physique, puis de chimie mercredi. La Suisse compte trois lauréats potentiels.
Particle physics is a basic science that forms our image of matter and the universe. However, the findings of this discipline also have practical applications that directly influence our daily lives. One example is the company DECTRIS AG in Baden-Dättwil. At the joint annual conference of the Austrian Physics Society (ÖPG), the Swiss Physical Society (SPS) and the Swiss Institute for Particle Physics (CHIPP) in Geneva in August, the company presented its latest business ventures.
