Flavour constraints on beyond the Standard Model scenarios

TL;DR

This paper reviews how flavour physics constraints, especially from rare B decays, limit beyond Standard Model theories and compares these limits with LHC discovery prospects, highlighting the role of the SuperIso program.

Contribution

It provides a comprehensive overview of flavour constraints on BSM models and illustrates their interplay with collider searches, including the use of the SuperIso tool.

Findings

Flavour constraints significantly restrict BSM parameter space.

Comparison shows complementarity between flavour physics and collider searches.

SuperIso is a useful tool for calculating flavour observables.

Abstract

The interplay of flavour and collider physics is entering a new era with the start-up of the LHC. During the past few years rare B decays and in particular b -> s gamma transitions have been extensively used and provided exciting opportunities for mapping possible routes beyond the SM. Flavour constraints play in this manner a complementary role to the direct searches. Here we present an overview of the existing flavour constraints on various models and show examples of comparison with the LHC discovery potentials. The SuperIso program which is dedicated to flavour physics observable calculations is also described briefly.
