Overview of flavour physics with focus on the MSSM and 2HDMs

TL;DR

This paper reviews key flavour-violation processes and their implications for two-Higgs-doublet models and the MSSM, focusing on processes like $F=2$ transitions, $B_s o$, $b o s\u0003$, and tauonic $B$ decays.

Contribution

It provides a concise overview of how specific flavour-violation processes constrain and inform the parameter space of 2HDMs and the MSSM.

Findings

Constraints from $F=2$ processes limit model parameters.

$B_s o$ decay measurements impact model viability.

Observations of $b o s\u0003$ and tauonic $B$ decays provide key tests for these models.

Abstract

In these proceedings we give a concise review of some selected flavour-violation processes and their implications for two-Higgs-doublet models (2HDMs) and the MSSM. The processes under investigation are $\Delta F=2$ processes, $B_s\to\mu^+\mu^-$, $b\to s\gamma$, and tauonic $B$ decays. For each process we show the impact on the models.
