Variations on Minimal Flavour Violation

Friday July 2nd, 2010, 14.30 hs - Seminar room

Speaker: Thorsten Feldmann (Technische Universitat Munchen)

Abstract: In this talk I will present some recent applications and extensions of the concept of "minimal flavour violation" (MFV), which is frequently used to constrain the flavour sector of new physics models. I will shortly explain how to define MFV in the effective-theory context, making use of Yukawa
spurion fields. Using the same language, the particular role of the top-quark in the SM can be embedded into the MFV approach, and also models beyond MFV can be systematically characterised. Finally, I speculate on the possibility to use the MFV ansatz to construct a dynamical theory for a spontaneously broken flavour symmetry.
