Abstract

In this work, we have studied lepton flavor violating (LFV) decays of ZZ gauge boson and Higgs boson (HH) in the scotogenic model. We have computed branching ratios for the decays ZαβZ\to\ell_\alpha\ell_\beta and HαβH\to\ell_\alpha\ell_\beta in this model. Here, α\ell_\alpha and β\ell_\beta are different charged lepton fields. After fitting to the neutrino oscillation observables in the scotogenic model, we have found that the branching ratios for the LFV decays of ZZ and HH can be as large as 108\sim10^{-8} and 103\sim10^{-3} respectively. However, after satisfying the constraints due to non-observation of αβγ\ell_\alpha\to\ell_\beta\gamma decays, the above mentioned branching ratio results are found to be suppressed by a factor of 107\sim10^{-7}.
