Z lepton flavour violation as a probe for new physics at future $e^{+}{e}^{-}$ colliders

Lorenzo Calibbi, Xabier Marcano, Joydeep Roy

In this work we assess the potential of discovering new physics by searching for lepton-flavour-violating (LFV) decays of the $Z$ boson, $Z\to {\ell }_i{\ell }_j$, at the proposed circu…
