Observability of Parameter Space for Charged Higgs Boson in its bosonic decays in Two Higgs Doublet Model Type-1

TL;DR

This paper investigates the parameter space for charged Higgs bosons decaying into W bosons and neutral scalars within the Type-I Two Higgs Doublet Model, highlighting potential discovery channels at current collider energies.

Contribution

It analyzes the viable parameter space for charged Higgs boson decays into bosonic channels, considering recent experimental and theoretical constraints, and proposes this as an alternative detection method.

Findings

Mass of 150 GeV for H± is most probable for bosonic decay channel.

The decay channel H±→W±ϕ is viable at √s=8, 13, 14 TeV.

Proposes this channel as an alternative to τ±ν decay mode.

Abstract

This study explores the possibility of discovering $H^{\pm}$ through its bosonic decays, i.e. $H^{\pm}\rightarrow W^\pm\phi$ (where $\phi$ = h or A), within the Type-I Two Higgs Doublet Model (2HDM). The main objective is to demonstrate the available parameter space after applying the recent experimental and theoretical exclusion limits. We suggest that for $m_{H^\pm}$ = 150 GeV is the most probable mass for the $H^\pm\rightarrow W^\pm\phi$ decay channel in $pp$ collisions at $\sqrt{s}$ = 8, 13 and 14 TeV. Therefore we propose that this channel may be used as an alternative to $H^\pm\rightarrow \tau^\pm\nu$.
