Exotic Higgs decays in a neutrino mass model with discrete S3 symmetry

Exotic Higgs decays can arise in lepton flavor models with horizontal symme- tries. We investigate the scalar sector of a neutrino mass model using an S3 family symmetry as an example. The model’s symmetry leads to an enlarged scalar sector with features that might be used to test the model experimentally, such as scalar particles with masses below 1 TeV and manifestly non-zero ma- trix elements for lepton flavor violating decays. We compare different decay channels of the scalars as well as leptonic processes that violate lepton flavor, in order to compare model predictions with experimental bounds
