Best wishes, Eric

Agenda May 27

* Time: 10.00 - 17.00 * Talk 10.30 - 10.45, H320 pre-talk question session * Talk 10.45-11.15, H320 Johannes Oberreuter (UvA): "The everpresent eta-problem: knowledge of all hidden sectors required" * Time: 15.00 - 16.00 Student meeting/discussion TBA: "TBA" * Talk 16.15-16.30-17.00, H320 Damien George (Nikhef) "A systematic approach to model building" I will discuss a technique that exhaustively determines all continuous symmetries of a set of equations, and show how this method can be applied to particle physics and model building. Given an arbitrary action with free parameters, one can systematically determine all possible symmetries, along with all parameter relationships that yield an enhanced symmetry group. If the action contains a symmetry that is spontaneously broken, the method determines the original symmetry, along with any field redefinition required to restore the non-broken phase. * 17.00 Borrel _______________________________________________ Theory-center mailing list Theory-center@nikhef.nl https://mailman.nikhef.nl/mailman/listinfo/theory-center
