Light charged Higgs at LHC

TL;DR

This paper investigates the detection prospects of a light charged Higgs boson at the LHC, focusing on its decay into a W boson and b-quarks, and analyzes the decay product distributions to aid discovery.

Contribution

It provides a detailed analysis of the decay channel H^+ → W^+bar{b} for light charged Higgs masses, including the distribution of decay products, which is novel for this mass range.

Findings

Decay product distributions are characterized for the H^+ → W^+bar{b} channel.

The analysis aids in distinguishing the light charged Higgs signal from background.

Results support the feasibility of detecting light charged Higgs in the specified mass range.

Abstract

The LHC program for discovery of light charged Higgs with mass 135-180 GeV has to take into account decay $H^+\to \bar{b}\,t^*\to W^+b\bar{b}$. The distribution of decay products in effective mass of $t^*=Wb$ is obtained.
