Zurich particle physicists make headlines with XENON collaboration

Axions are elementary particles with extremely low mass. So far they exist only in the brains of theoretical physicists, nobody has observed them. Really? Measurement results at detector XENON1T in Italy make one sit up and take notice.

Claudia Merlassino wins the CHIPP Prize 2020

Claudia Merlassino was born in Genoa, studied physics in Milan and completed her doctorate at the University of Bern in October 2019, since then she has been doing research at Oxford University in the UK. 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.

Cinq élèves de secondaire remportent l’or aux Olympiades virtuelles suisses de physique 2020

La finale des olympiades de physique aurait dû avoir lieu en mars. En raison de la pandémie du coronavirus, les examens ont été reportés au 6 juin et organisés en ligne. Les 24 finalistes ont testé leurs connaissances depuis la maison. Le suspense était à son comble lors de l’annonce des résultats le 27 juin.

Surprising Signal in Dark Matter Detector

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.

Early Years of the Laser in Switzerland

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.

Exploring new ways to see the Higgs boson

This media update is part of a series related to the 2020 Large Hadron Collider Physics conference, which took place from 25 to 30 May 2020. Originally planned to take place in Paris, the conference was held entirely online due to the COVID-19 pandemic.

CERN collaborations present new results on charmed particles at online conference

The ALICE, CMS and LHCb collaborations present new measurements that show how particles containing charm quarks can serve as “messengers” of hadrons and the quark–gluon plasma, carrying information about these forms of matter.
This media update is part of a series related to the 2020 Large Hadron Collider Physics (LHCP2020) conference, taking place 25–30 May 2020.

The start-up Positrigo uses findings from particle physics for the early diagnosis of Alzheimer's disease

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.

Swiss research initiative CHART works on particle accelerators of the future

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 fêlure dans le miroir de la nature

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.
