Exotic Higgs decays in a neutrino mass model with discrete S₃ symmetry — Gautam Bhattacharyya¹, •Philipp Leser², and Heinrich Päs² — ¹Saha Institute of Nuclear Physics, Kolkata, India — ²Technische Universität Dortmund, Germany

Exotic Higgs decays can arise in lepton flavor models with horizontal symmetries. 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 matrix 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.
