Sensitivity of future lepton colliders to the search for charged lepton flavor violation

Understand

The observation of lepton flavor violation indicates new physics beyond the Standard Model.

• Lepton colliders are ideal facilities to probe charged lepton flavor violation (CLFV) signals induced by new physics at high energy.
• In this work we perform a comprehensive study of the sensitivity of future lepton colliders to charged lepton flavor violation.
• We consider the most general renormalizable Lagrangian coupling two leptons to new bosonic particles, involving both $\Delta L=0$ and $\Delta L=2$ interactions.
