在LHC上带电希格斯玻色子和单个顶夸克的联合产生

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

Yao-Bei Liu, Jie-Fen Shen

摘要:

左右孪生希格斯粒子(LRTH)模型预言了带电希格斯粒子$ϕ^{\pm}$的存在。本文研究了在$CERN$大型强子对撞机(LHC)上通过$bg\to tϕ^{-}$过程产生带顶夸克的带电希格斯玻色子$ϕ^{-}$。数值计算结果表明,在合理的LRTH模型参数空间内,生产截面可以达到$10 pb$的水平。我们希望,只要它不是太重,重电荷希格斯玻色子玻色子$ϕ^{-}$的可能特征可以通过LHC实验中的衰变模式$ϕ^{-}\to \bar{t}b$检测到。

英文摘要:

The left-right twin Higgs(LRTH) model predicts the existence of the charged Higgs $ϕ^{\pm}$. In this paper, we study the production of the charged Higgs boson $ϕ^{-}$ with single top quark via the process $bg\to tϕ^{-}$ 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 $ϕ^{-}$ might be detected via the decay mode $ϕ^{-}\to \bar{t}b$ at the LHC experiments.
