Current status of MSSM Higgs sector with LHC 13 TeV data

TL;DR

This paper reviews the current status of the MSSM Higgs sector in light of recent LHC 13 TeV data, highlighting how new experimental results constrain the model's parameter space and exploring potential decay scenarios.

Contribution

It provides a comprehensive analysis of the impact of recent LHC Run-II data on the MSSM Higgs sector, including constraints from heavy Higgs searches and rare B meson decays.

Findings

High $ aneta$ regions are disfavored by $H/A o au^+ au^-$ searches.

Recent B meson decay results impose stronger constraints on low $ aneta$ and low $M_A$.

Run-II Higgs signal strength data is comparable to Run-I in constraining the model.

Abstract

ATLAS and CMS collaborations have reported the results on the Higgs search analyzing $\sim 36$ fb$^{-1}$ data from Run-II of LHC at 13 TeV. In this work, we study the Higgs sector of the phenomenological Minimal Supersymmetric Standard Model, in light of the recent Higgs data, by studying separately the impact of Run-I and Run-II data. One of the major impacts of the new data on the parameter space comes from the direct searches of neutral CP-even and CP-odd heavy Higgses ($H$ and $A$, respectively) in the $H/A \to \tau^{+} \tau^{-}$ channel which disfavours high $\tan\beta$ regions more efficiently than Run-I data. Secondly, we show that the latest result of the rare radiative decay of $B$ meson imposes a slightly stronger constraint on low $\tan \beta$ and low $M_A$ region of the parameter space, as compared to its previous measurement. Further, we find that in a global fit Run-II light Higgs signal strength data is almost comparable in strength with the corresponding Run-I data. Finally, we discuss scenarios with the Heavy Higgs boson decaying into electroweakinos and third generation squarks and sleptons.
