Associated production of the charged Higgs boson and single top quark at the LHC

TL;DR

This paper investigates the production of charged Higgs bosons in the LRTH model at the LHC, showing potential for detection through specific decay channels if the Higgs is not too heavy.

Contribution

It provides a detailed analysis of charged Higgs production via single top quark processes in the LRTH model at the LHC, including cross section estimates and detection prospects.

Findings

Production cross section can reach 10 pb in the LRTH model.

Heavy charged Higgs bosons may be detectable via decay to t̄b.

Potential signatures could be observed at the LHC if the Higgs is not too heavy.

Abstract

The left-right twin Higgs(LRTH) model predicts the existence of the charged Higgs $\phi^{\pm}$. In this paper, we study the production of the charged Higgs boson $\phi^{-}$ with single top quark via the process $bg\to t\phi^{-}$ at the $CERN$ Large Hadron Collider(LHC). The numerical results show that the production cross section can reach the level of $10 pb$ in the reasonable parameter space of the LRTH model. We expect that, as long as it is not too heavy, the possible signatures of the heavy charged Higgs boson $\phi^{-}$ might be detected via the decay mode $\phi^{-}\to \bar{t}b$ at the LHC experiments.
