Flavour Physics in the LHC Era

Abstract

These lectures give a topical review of heavy flavour physics, in particular CP violation and rare decays, from an experimental point of view. They describe the ongoing motivation to study heavy flavour physics in the LHC era, the current status of the field emphasising key results from previous experiments, some selected topics in which new results are expected in the near future, and a brief look at future projects.

Three-loop SM beta-functions for matrix Yukawa couplings

“…where the commutator [Y u , Y d ] is an anti-hermitian matrix, which is a measure of whether Y u and Y d can be diagonalized simultaneously, 5 and h l is used to indicate l-loop contribution. Due to the unbroken SU (2) invariance, we have Z1/2 uL = Z1/2 dL = Z1/2 QL .…”

“…Irrespectively of the considered vertex the results for Y f turn out to be the same. 5 It is interesting to note that det [Yu,…”
