Charged Higgs Production in Association With W^{\pm} at Large Hadron Colliders

TL;DR

This paper investigates the production of charged Higgs bosons in association with W bosons at large colliders within the littlest Higgs and left-right twin Higgs models, highlighting potential observable cross sections.

Contribution

It provides the first detailed analysis of W^b1}H^b1} production cross sections in these models, emphasizing their detectability at 14 TeV colliders.

Findings

Littlest Higgs models predict cross sections up to hundreds of femtobarns.

Left-right twin Higgs models have roughly ten times lower production rates.

Large cross sections suggest potential for experimental probing of charged Higgs in these models.

Abstract

Many new physics models beyond the standard model, such as the littlest higgs models and the left right twin higgs models, predict the existence of the large charged higgs couplings H^-q\bar b and H^+b\bar q, where q=t or the new vector-like heavy quark T; On the other hand, some new physics models like the littlest higgs also predict the gauge-higgs couplings. Such couplings may have rich collider phenomenology. We focus our attention on these couplings induced by the littlest higgs models and the left right twin higgs models models and consider their contributions to the production cross section for W^\pm H^\mp production at the large hadron colliders. We find that the cross sections, in the littlest higgs models, on the parton level gg \to W^\pm H^\mp and q\bar q \to W^\pm H^\mp (q=u,d,s,c,b) may reach tens of several dozen femtobarns in reasonable parameters space at the collision energy of 14 TeV and that the total cross section can even reach a few hundred femtobarns in certain favored space. While in the left right twin higgs models, the production rates are basically one order lower than these in littlest higgs. Therefore, due to the large cross sections of that in the littlest higgs, it may be possible to probe the charged higgs via this process in a large parameter space.
