Deviation from μ−τ symmetry and lepton flavor violation with generalized CP transformations

In the model [J. Ganguly and R. S. Hundi, Chinese Phys. C 46, 103101 (2022).], the neutrino mixing has been explained in a type II seesaw scenario with generalized [Formula: see text] symmetries. The neutrino mass matrix has [Formula: see text] symmetric nature. As neutrino oscillation data suggests neutrino mixing can deviate from [Formula: see text] symmetry, in this work, deviation from [Formula: see text] symmetric mass matrix is shown by breaking the generalized [Formula: see text] symmetry explicitly by a small amount in the Yukawa Lagrangian which actually shows that atmospheric mixing angle can deviate from maximal value. As a phenomenological implication, branching ratios of the lepton flavor violating decays have been studied, which occurs by the triplet Higgs, by writing down the full scalar potential and then finding the mass eigenstates of the scalars. We have studied the implications of neutrinoless double beta decay within our model.
