Abstract
Lepton flavor violating processes are highly suppressed in the Standard Model. Therefore, if observed, lepton flavor violation would be a clear indication of new physics beyond the Standard Model. We study the process $e^+e^-\to\tau\mu$ at tree-level in the Standard Model Effective Field Theory both on the $Z$-pole and at higher center-of-mass energies. We show that the constraints derived from the future circular $e^+e^-$ colliders FCC-ee and CEPC, are complementary to those obtained from low-energy tau decays at BaBar and Belle, as well as projections from Belle-II.

Report
Limits on the lepton flavor violating process e+e- -> tau mu have been studied at the Z pole and higher energies. Constraints derived from future colliders are complementary to those that have been or can be obtained from tau decays at Belle, Babar and Belle II.
