BSM Higgs在LHC上寻找胶子融合过程pp -> h +喷流-> tau^+ tau^- +喷流

BSM Higgs searches in the gluon fusion process pp -> h +jet -> tau^+ tau^- + jet at the LHC

摘要:

标准模型(SM)希格斯玻色子的质量被大型电子正电子对撞机(LEP)限制在114.4 GeV以上。简单地扩展标量扇区,比如增加单线态和/或双线态,可以通过减少与规范玻色子的耦合,使最轻的希格斯粒子变得更轻。这样一个轻的希格斯粒子可能躲过了LEP的搜索,但在大型强子对撞机(LHC)的过程pp -> h j -> tau^+ tau^- j中被探测到,其中j是一个解析的喷流。我们的结论是,在一些超越标准模型(BSM)扩展的标量部门,一个非常轻的希格斯状态可以检测到在14 TeV的LHC的早期数据。

英文摘要:

The mass of the Standard Model (SM) Higgs boson was constrained by the Large Electron-Positron (LEP) collider to be above 114.4 GeV. Simple extensions of the scalar sector like adding singlets and/or doublets allow the lightest Higgs to be much lighter via a reduction in its coupling to gauge bosons. Such a light Higgs could have evaded the LEP searches but could be detected at the Large Hadron Collider (LHC) in the process pp -> h j -> tau^+ tau^- j, where j is a resolved jet. We conclude that in some Beyond the Standard Model (BSM) extensions of the scalar sector, a very light Higgs state could be detected at the 14 TeV LHC with early data.
