H± in the W±h channel at the LHC Run 2

We analyse the discovery prospects of the charged Higgs boson,

$H^\pm$ , via its decay in the

$W^\pm h$ channel in the minimal supersymmetric Standard Model (MSSM) as well as several 2-Higgs Doublet Models (2HDMs).

$h$ , the lightest scalar Higgs boson in these models, is identified with the recently discovered

$\sim 125$ GeV state,

$H_\text{obs}$ , at the Large Hadron Collider (LHC). We find that, while it provides an important input in the kinematic selection of signal events, the measured

$H_\text{obs}$ mass renders this channel inaccessible in the MSSM. In the 2HDMs though, through a dedicated signal-to-background analysis for the

$pp\to t(\bar{b})H^-\to \ell^\pm\nu_\ell jj bb\bar{b}(\bar{b})$ +h.c process, we establish that some parameter space regions will be testable at the LHC with

$\sqrt{s}=14$ TeV.

Abstract

We analyse the discovery prospects of the charged Higgs boson, $H^\pm$ , via its decay in the $W^\pm h$ channel in the minimal supersymmetric Standard Model (MSSM) as well as several 2-Higgs Doublet Models (2HDMs). $h$ , the lightest scalar Higgs boson in these models, is identified with the recently discovered $\sim 125$ GeV state, $H_\text{obs}$ , at the Large Hadron Collider (LHC). We find that, while it provides an important input in the kinematic selection of signal events, the measured $H_\text{obs}$ mass renders this channel inaccessible in the MSSM. In the 2HDMs though, through a dedicated signal-to-background analysis for the $pp\to t(\bar{b})H^-\to \ell^\pm\nu_\ell jj bb\bar{b}(\bar{b})$ +h.c process, we establish that some parameter space regions will be testable at the LHC with $\sqrt{s}=14$ TeV.
