Young@INFN 2025: 4th event - MEG II experiment

by Susanna Scarpellini (Istituto Nazionale di Fisica Nucleare)

Thursday 29 May 2025, 16:30 → 18:30 Europe/Rome

Sala 5A (Dipartimento di Fisica - Edificio Fermi)

Speaker: Susanna Scarpellini

Titolo:
"Searching for New Physics at the Intensity Frontier: MEG II and future μ → e γ experiments"

Abstract:
"The MEG II experiment, located at the Paul Scherrer Institute (PSI, Switzerland), uses a high-intensity muon beam to search for the Charged Lepton Flavor Violating decay μ^+→ e^+  γ. An experimental observation of this process would provide evidence of New Physics (NP) beyond the Standard Model. Conversely, in the absence of signal, setting strong bounds on its branching ratio helps constrain NP theoretical models. 
MEG II currently holds the most stringent upper limit on the branching ratio of this decay and will continue collecting data until the end of 2026 to further improve its sensitivity. 
In the (near) future, higher-intensity muon beams will be available. This talk will explore what future μ → e γ experiments might look like, particularly focusing on a possible photon detection technique: the pair conversion approach."
