在CERN LHC 3-3-1模型中产生带电希格斯玻色子

Production of Charged Higgs Bosons in a 3-3-1 Model at the CERN LHC

A. Alves, E. Ramirez Barreto, A. G. Dias

摘要:

我们进行了研究的带电Higgs生产的$SU(3)_{C}\otimes SU(3)_{L}\otimes U(1)_{X}$模型与右手中微子,假定保管对称性,减少了数量的自由参数的标量势。我们计算了典型和新的生产模式的带电标量的截面。新的$SU(3)_{L}$中性规范玻色子之一,$Z^{\prime}$,影响一些产生截面,将该模型与其他标准模型扩展区分开来,例如,最小超对称标准模型和一般的两个希格斯双重态模型。与MSSM相比,在强子对撞机上,模型中希格斯部分和$Z^{\prime}$规范玻色子之间的相互作用大大提高了最轻带电希格斯玻色子$H_{1}^{\pm}$的所有产生率。我们发现,大部分的参数空间可以探测在LHC运行在14 TeV的质心能量在相关的$pp\rightarrow W^{\pm}H_{1}^{\mp}+X$生产通道在低光度运行阶段的实验。

英文摘要:

We perform a study of the charged Higgs production from an $SU(3)_{C}\otimes SU(3)_{L}\otimes U(1)_{X}$ model with right-handed neutrinos, postulating a custodial symmetry which reduces the number of free parameters in the scalar potential. We compute the cross sections for charged scalars for typical and new production modes. One of the new $SU(3)_{L}$ neutral gauge bosons, $Z^{\prime}$, affects some production cross sections distinguishing the model from other Standard Model extensions like, for example, the Minimal Supersymmetric Standard Model and general two Higgs doublets models. The interplay between the Higgs sector of the model and that $Z^{\prime}$ gauge boson enhances substantialy all the production rates of the lightest charged Higgs boson, $H_{1}^{\pm}$, at hadron colliders compared to the MSSM. We found that a large portion of the parameters space can be probed at the LHC running at 14 TeV center-of-mass energy in the associated $pp\rightarrow W^{\pm}H_{1}^{\mp}+X$ production channel in the low luminosity run stage of the experiment.
