In Search of New Physics: New Result from the MEG II Collaboration
On the occasion of a special seminar at the Paul Scherrer Institut (PSI) in Switzerland on 23 April 2024 the scientific collaboration of the MEG II experiment presented an important new result in the search for the decay of a positive muon into a positron and a photon. The findings, based on data collected in 2021 and 2022, are detailed in a paper published on arXiv and submitted to the journal Physical Review Letters.

Magnetically shielded from the rest of the world
At the Paul Scherrer Institute PSI, researchers together with a company have constructed a room that is one of the best magnetically shielded places on the earth. With its help, they want to solve the last mysteries of matter and answer a fundamental question: Why does matter - and thus why do we - exist at all?
