LHeC上的希格斯玻色子和Hbbar耦合

Higgs Boson Searches and the Hbbar Coupling at the LHeC

T. Han, B. Mellado

摘要:

一旦希格斯玻色子玻色子的存在在欧洲核子研究中心的大型强子对撞机(LHC)上得到证实,人们的注意力将转向理解它与其他粒子的耦合。一个关键的方面是底部汤川耦合的测量,这是在LHC的挑战。在本文中,我们研究了使用前向喷流标记作为一种手段,以确保观察和显着提高希格斯玻色子信号的纯度在H到bbar衰变模式从深非弹性电子-质子散射在大型强子对撞机。我们证明了在带电电流事件中前向喷流标记的要求强烈地增强了信号背景比。还讨论了否决权对额外部分子的影响。对强子簇射的良好响应和b标记能力是探测器性能的关键方面。

英文摘要:

Once the existence of the Higgs boson is established at the CERN Large Hadron Collider (LHC), the focus will be shifted toward understanding its couplings to other particles. A crucial aspect is the measurement of the bottom Yukawa coupling, which is challenging at the LHC. In this paper we study the use of forward jet tagging as a means to secure the observation and to significantly improve the purity of the Higgs boson signal in the H to bbar decay mode from deep inelastic electron-proton scattering at the LHC. We demonstrate that the requirement of forward jet tagging in charged current events strongly enhances the signal-to-background ratio. The impact of a veto on additional partons is also discussed. Excellent response to hadronic shower and b-tagging capabilities are pivotal detector performance aspects.
