B. E. Cox, F. K. Loebinger, A. D. Pilkington

摘要:

本文详细研究了在LHC的中心排他产生过程中在b衰变通道中寻找希格斯玻色子的工作。我们目前的质子标记探测器在220米和420米左右的ATLAS或CMS的结果。我们考虑两个基准方案:一个标准模型(SM)希格斯玻色子和最小超对称标准模型(MSSM)的m_h^{max}方案。检测器接受,涂抹和事件触发策略被认为是。我们发现,SM希格斯粒子将是具有挑战性的观察在b喷道没有改进目前提出的实验配置,但是在b-喷流通道中可以观察到中性标量MSSM希格斯玻色子,在2 x 10^{33} cm^{-2} s^{-1}和10^{34} cm^{-1}之间的所有亮度下,在三年内采集的数据的意义为3 sigma或更大。2} s^{-1},在某些情况下,三年后达到5 sigma或更高。

英文摘要:

A detailed study is presented of the search for Higgs bosons in the b-decay channel in the central exclusive production process at the LHC. We present results for proton tagging detectors at both 220m and 420m around ATLAS or CMS. We consider two benchmark scenarios; a Standard Model (SM) Higgs boson and the m_h^{max} scenario of the Minimal Supersymmetric Standard Model (MSSM). Detector acceptance, smearing and event trigger strategies are considered. We find that the SM Higgs will be challenging to observe in the b-jet channel without improvements to the currently proposed experimental configuration, but a neutral scalar MSSM Higgs Boson could be observable in the b-jet channel with a significance of 3 sigma or greater within three years of data taking at all luminosities between 2 x 10^{33} cm^{-2} s^{-1} and 10^{34} cm^{-2} s^{-1}, and at 5 sigma or greater after three years in certain scenarios.
