The next generation of $\mu\ -> e \gamma$ and $\mu\ -> 3e$ CLFV search experiments

Understand

We explore the possibilities for extending the sensitivity of current searches for the charged lepton flavor violating decays $\mu\ -> e \gamma$ and $\mu\ -> eee$.

• A future facility such as Project X at Fermilab could provide a much more intense stopping $\mu^+$ beam, facilitating more sensitive searches, but improved detectors will be required as well.
• Current searches are limited by accidental and physics backgrounds, as well as by the total number of stopped muons.
• One of the limiting factors in current detectors for $\mu\ -> e \gamma$ searches is the photon energy resolution of the calorimeter.
