Abstract
In this work, we explore lepton flavour violating (LFV) decays of the Z and Higgs boson in Alternative Left-Right Model that extend the Standard Model field content and gauge structure. The presence of exotic fermions, additional gauge bosons, and charged scalar fields in these scenarios can induce LFV processes through I-loop and mixing effects. We evaluate the 1-loop branching ratios for decays such as Z -t et,e1and h -t etej (i -=t- j), taking into account current experimental constraints on exotic field masses, and flavour-violating observables. A random scan of the model parameters is performed to systematically examine the phenomenology of these decay channels. We show that we can obtain significant enhancement for these rare decays, which can be explored at the Large Hadron Collider (LHC) and future colliders. Numerical analyses are performed to identify viable regions of parameter space where the predicted LFV signals are enhanced. The results indicate that several LFV decay channels may reach sensitivities accessible to present and future collider experiments, providing an important probe of new physics associated with these scenarios.
