Lepton-Flavor violation in a neutrino mass model with discrete S3 symmetry — •Philipp Leser and Heinrich Päs — Institut für Physik, TU Dortmund, 44221 Dortmund, Germany
A discrete family symmetry using the group S3 is able to explain the observed maximal mixing in the lepton sector while maintaining the ability to generate the observed CKM angles (Chen, Frigerio, Ma, hep-ph/0404084). The model requires an enlarged Higgs sector which includes features that might be used to test the model experimentally, such as scalar Higgs particles with different masses and manifestly non-zero matrix elements for lepton flavor violating decays. We investigate distinct channels, in particular lepton flavor violating ones, and compare model predictions with experimental bounds and predictions of alternative scenarios.
