TL;DR
The Mu3e experiment aims to detect rare lepton-flavor-violating decays, significantly improving sensitivity and exploring new physics beyond current limits, including dark photons and other exotic particles.
Contribution
It introduces a new experimental setup that enhances sensitivity to rare decays and extends searches to additional exotic particles, complementing existing physics programs.
Findings
Projected sensitivity improvement by four orders of magnitude
Potential to discover or set new limits on lepton-flavor violation
Extended search capabilities for dark photons and long-lived particles
Abstract
The Mu3e experiment at the Paul Scherrer Institut will search for the lepton-number-violating decay \mueee, extending the sensitivity by four orders of magnitude compared to existing limits. This probe of new physics is complementary to the existing collider, dark matter and neutrino particle physics programmes, and part of a global programme investigating the charged lepton flavour sector. As well as the main \mueee search, Mu3e will also extend the sensitivity to low-mass dark photons, and additional flavour-violating decays involving long-lived or stable particles.
