Flavor and CP violations from sleptons at the muon collider

Original · EN

Supersymmetric theories generally have new flavor and CP violation sources in the squark and slepton mass matrices. They will contribute to the lepton flavor violation processes, such as μ→ e γ, which can be probed far below the current bound with an intense muon source at the front end of the muon collider. In addition, if sleptons can be produced at the muon collider, the flavor violation can occur at their production and decay, allowing us to probe the flavor mixing structure directly. Asymmetry between numbers of μ+ e- and e+ μ- events will be a sign for CP violation in supersymmetric flavor mixing.
