| Finite family symmetries in the lepton sector |
| Speaker: | Patrick Otto Ludl (Uni Wien) |
| Abstract: | The fact that at least two of the three known active neutrinos have non-vanishing masses is the most important evidence for physics beyond the standard model of particle physics. In the same way as the introduction of quark mass terms leads to quark mixing, the introduction of neutrino mass terms leads to lepton mixing in charged current interactions. While in the quark-sector the mixing matrix is close to the unit matrix, in the lepton sector this is not the case. In fact in the lepton sector two of the three mixing angles are quite large. An interesting possibility to "explain" these large values for the mixing angles is to impose certain symmetries on the actions of the leptonic and scalar sector, the most popular symmetry groups being finite groups. After an introduction to the physics of lepton mixing we will take a look on the mathematics of finite groups. Finally we will study some simple models using finite groups in order to reproduce some of the features required to accommodate the experimental results. |
