Title: Lepton-flavour-violating Z and quarkonium decays
Abstract:
Within an effective field theory approach, the potential of discovering new physics searching for lepton flavour violating (LFV) decays of Z bosons and quarkonia is discussed. In particular, the expected sensitivities of future high-energy e+e- colliders (FCC-ee/CEPC) and flavour factories are compared with indirect limits set on these processes by LFV muon and tau decays.
