在LHC独家生产MSSM希格斯玻色子

Exclusive production of the MSSM Higgs bosons at the LHC

Sven Heinemeyer, Valery A. Khoze, Marek Tasevsky, Georg Weiglein

摘要:

我们回顾了在LHC上使用前向质子探测器进行BSM希格斯玻色子的中心独占生产(CEP)的前景,该探测器建议安装在距离ATLAS和/或CMS 220 m和420 m处。结果MSSM在标准的基准场景和场景兼容的冷暗物质遗迹丰度和其他精密测量。根据LHC希格斯玻色子搜索的结果,我们研究了一个假设,即在125 GeV的质量下发现的候选者与轻CP甚至MSSM希格斯玻色子玻色子兼容。我们发现CEP可以提供有关希格斯玻色子的自旋宇称性质的有价值的信息。

英文摘要:

We review the prospects for Central Exclusive Production (CEP) of BSM Higgs bosons at the LHC using forward proton detectors proposed to be installed at 220 m and 420 m from the ATLAS and/ or CMS. Results are presented for MSSM in standard benchmark scenarios and in scenarios compatible with the Cold Dark Matter relic abundance and other precision measurements. Following results of the LHC Higgs boson searches, we investigate a hypothesis that candidates found at a mass of 125 GeV are compatible with light CP-even MSSM Higgs bosons. We show that CEP can give a valuable information about spin-parity properties of the Higgs bosons.
