Tauonic B decays in 2HDMs and the MSSM in the decoupling limit

TL;DR

This paper reviews how 2HDMs and MSSM can explain deviations in tauonic B decays, focusing on flavor violation and two-loop SQCD corrections to Higgs-quark couplings.

Contribution

It presents a detailed analysis of tauonic B decay anomalies within 2HDMs of type III and discusses the matching of MSSM to 2HDM, including new two-loop SQCD corrections.

Findings

Explains BABAR anomalies with 2HDM type III involving flavor violation.

Calculates two-loop SQCD corrections to Higgs-quark couplings in MSSM.

Provides insights into flavor physics and Higgs interactions in beyond Standard Model theories.

Abstract

In these proceedings we review two aspects of 2HDMs with generic Yukawa structures. The first part considers how recent deviations from the SM expectations in tauonic B decays (observed by BABAR) can be explained in a 2HDM of type III with sizable flavour violation in the up-sector. The second part discusses the matching of the MSSM on the 2HDM of type III. Here we focus on the recently calculated two-loop SQCD corrections to the Higgs-quark-quark couplings.
