[PAST EVENT] PHYSICS HIGH ENERGY THEORY SEMINAR

2pm - 3pm
Abstract: Recent experimental data suggest that the leptonic mixing matrix, one of the chief unsolved problems in elementary particle physics, is very close to the so-called "tribimaximal form". Such a structure is natural in the context of permutation symmetry. Inspired by this we implement the S3 group as a zeroth order approximation into the electroweak theory and S2 subgroups of it as first order and second order perturbations.
