Particle Physics

Particle physics probes the basic building blocks of matter and their interactions, which determine the structure and properties of the extreme diversity of matter in the universe. It aims at explaining what holds the world together in its most fundamental constituents.

Modern physics relies on an elegant «Standard Model of particle physics», a quantum field theory based on three symmetries and a symmetry breaking. This theory describes and explains magnificently all experimental results obtained so far. With the discovery of the Higgs particle in 2012 at the Large Hadron Collider at CERN, the last missing piece of the Standard Model has been experimentally confirmed. Experiments at CERN and at other international laboratories now continue to test the validity and limits of the Standard Model in ever widening scope. However, for a comprehensive understanding of the laws of nature a theory beyond the Standard Model is needed, which should include gravitation and explain the presence of dark matter and dark energy in the universe.

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.

Fünf Mittelschüler gewinnen Gold an virtueller Schweizer Physik-Olympiade 2020

Das Finale der Physik-Olympiade hätte eigentlich schon im März stattfinden sollen. Wegen der Coronavirus-Pandemie wurden die Prüfungen auf den 6. Juni verschoben und online durchgeführt. Die 24 Finalistinnen und Finalisten stellten ihr Können von zuhause aus unter Beweis. Als am 27. Juni die Resultate verkündet wurden, war die Spannung gross.

Swiss physicists in dialog with the society

Swiss physicists want to make their fascinating research understandable to the interested public and to debate its meaning for our society together with representatives of other fields.
