Description

Searches for charged lepton flavor violation in the muon sector stand out among the most sensitive and clean probes for New Physics. Currently, $\mu^+ \to e^+ \gamma$ experiments provide the best constraints for a wide range of models while new experiments investigating the processes of $\mu^+ \to e^+e^+e^-$ and $\mu \to e$ conversion in the nuclear field are anticipated to reach comparable or higher sensitivities.
The High-Intensity Muon Beam (HIMB) facility at PSI (CH), which is expected to deliver muon beam intensities up to two orders of magnitude higher than the existing beam lines, offers a unique opportunity to significantly enhance the sensitivity of $\mu^+ \to e^+ \gamma$ searches. The discovery potential could be substantially boosted and a sensitivity comparable to that of all the other projects could be reestablished, which is essential for discriminating among competing new-physics scenarios should an observation occur in any of the channels.
We will present a plan for a future $\mu^+ \to e^+ \gamma$ experimental program at HIMB, aiming at improving, within the next decade, the sensitivity of the $\mu^+ \to e^+ \gamma$ search by more than one order of magnitude relative to the expected final result of the current leading experiment, MEG II.
