Searches for $pp\rightarrow H^{\pm}h\rightarrow W^{\pm}hh$ signal in the MSSM model

TL;DR

This paper investigates a nearly background-free signature of charged Higgs bosons in the MSSM at the LHC, analyzing production and decay processes to identify promising detection points.

Contribution

It introduces a new experimental signature for charged Higgs detection in MSSM, using updated theoretical parameters and simulation tools to identify optimal production and decay conditions.

Findings

Production cross sections are largest at Benchmark Point 4.

Branching ratios are maximized at Benchmark Point 14.

The signature is promising for supersymmetry studies at 13 and 14 TeV.

Abstract

We considered the new signature of a charged Higgs boson, $pp\rightarrow H^{\pm}h\rightarrow W^{\pm}hh$, which is almost background free as the promising to study of supersymmetry at the LHC with both $\sqrt{s} = 13$ TeV and $\sqrt{s}= 14$ TeV. In the framework of MSSM model we used the latest theoretical parameter space, which is consistent with the experimental constraints from Large Hadron Collider and direct or indirect searches. In the surviving regions with the help of Pythia 8.3 and Feynhiggs programs it was found that production cross sections, $\sigma(pp\rightarrow H^{\pm}h)$, and Branching Ratios, $BR(H^{\pm}\rightarrow W^{\pm}h)$, are the largest at Benchmark Points 4 and 14 correspondingly.
