Experimental constraints from flavour changing processes and physics beyond the Standard Model

TL;DR

This paper reviews how flavour physics experiments constrain theories beyond the Standard Model by analyzing recent results from LHC and LHCb on CP violation, meson mixing, and rare decays.

Contribution

It provides an updated overview of experimental bounds on new physics from flavour-changing processes in charm and beauty sectors.

Findings

Stringent bounds on new physics parameters from recent experiments

Confirmation of the ongoing relevance of flavour studies in particle physics

Enhanced constraints from LHCb and early LHC results

Abstract

Flavour physics has a long tradition of paving the way for direct discoveries of new particles and interactions. Results over the last decade have placed stringent bounds on the parameter space of physics beyond the Standard Model. Early results from the LHC, and its dedicated flavour factory LHCb, have further tightened these constraints and reiterate the ongoing relevance of flavour studies. The experimental status of flavour observables in the charm and beauty sectors is reviewed in measurements of CP violation, neutral meson mixing, and measurements of rare decays.
