The Quest for \(\mu \to e \gamma\) and its Experimental Limiting Factors at Future High Intensity Muon Beams

The search for the Lepton Flavor Violating decay \(\mu \to e \gamma\) exploits the most intense continuous muon beams, which can currently deliver \(\sim 10^8\) muons per second. In the next decade, accelerator upgrades are expected in various facilities, making it feasible to have continuous beams...

Description
Summary:The search for the Lepton Flavor Violating decay \(\mu \to e \gamma\) exploits the most intense continuous muon beams, which can currently deliver \(\sim 10^8\) muons per second. In the next decade, accelerator upgrades are expected in various facilities, making it feasible to have continuous beams with an intensity of \(10^9\) or even \(10^{10}\) muons per second. We investigate the experimental limiting factors that will define the ultimate performances, and hence the sensitivity, in the search for \(\mu \to e \gamma\) with a continuous beam at these extremely high rates. We then consider some conceptual detector designs and evaluate the corresponding sensitivity as a function of the beam intensity.
