Description

Abstract:

A new set of experiments will deliver in the next few years unprecedented sensitivity to Lepton Flavor Violating (LFV) muon decays. Mu3e, proposed at PSI (Switzerland), will focus on observing $\mu\to 3e$ decays, with a projected target of $10^{15}$ muons decaying at rest, and excellent electron/positron track reconstruction. In this talk I will review the current and future statues of these probes, and I will delve in the potential of Mu3e to search for New Physics. Firstly, I will identify new room for CP violation in LFV observables, showing that CP violation from heavy states can make its first appearance in lepton flavor violating muon decays rather than in the electric dipole moment of the electron. Secondly, I will show that Mu3e has unique sensitivity for new light particles decaying displaced and produced in two-body, three-body and four-body decays of the muon, providing a complimentary opportunity to probe large portions of unexplored parameter space.

Biography

I graduated as PhD at the University of Cincinnati (Ohio, USA) in 2020, under the supervision of Prof. Jure Zupan. I was a postdoc at the Institute Jozef Stefan in Ljubljana, Slovenia, until 2023, and presently I have a research assignment at INFN - Section of Firenze. I work mainly in exploring the phenomenology of new physics models in flavor, neutrino, and dark matter physics.
