LHC中的SUSY希格斯玻色子

SUSY Higgs bosons at the LHC

Georg Weiglein

摘要:

综述了LHC中MSSM希格斯粒子物理的最新研究结果。分析了b \bar b H/A,H/A \to τ^+τ^-通道中LHC发现范围对超对称性的依赖性。这是通过将最新的CMS实验灵敏度结果(积分亮度为30或60 fb^-1)与MSSM希格斯玻色子性质的最新理论预测相结合来实现的。结果解释的参数管理MSSM希格斯部门在最低阶,M_A和tan_beta。虽然希格西诺质量参数μ对预期的发现范围(以及相应的“LHC楔”区域)有重大影响,但发现范围相对于其他超对称参数的变化相当稳定。在发现区域内,以1-4%的精度确定重中性希格斯玻色子玻色子的质量似乎是可行的。此外,它表明,希格斯玻色子的生产在中央专属衍射通道可以提供重要的信息的中性MSSM希格斯玻色子的属性。

英文摘要:

Recent results on MSSM Higgs physics at the LHC are reviewed. The dependence of the LHC discovery reach in the b\bar b H/A, H/A \to τ^+τ^- channel on the underlying SUSY scenario is analysed. This is done by combining the latest results for the prospective CMS experimental sensitivities for an integrated luminosity of 30 or 60 fb^-1 with state-of-the-art theoretical predictions of MSSM Higgs-boson properties. The results are interpreted in terms of the parameters governing the MSSM Higgs sector at lowest order, M_A and tan_beta. While the higgsino mass parameter μhas a significant impact on the prospective discovery reach (and correspondingly the ``LHC wedge'' region), it is found that the discovery reach is rather stable with respect to variations of other supersymmetric parameters. Within the discovery region a determination of the masses of the heavy neutral Higgs bosons with an accuracy of 1-4% seems feasible. It is furthermore shown that Higgs-boson production in central exclusive diffractive channels can provide important information on the properties of the neutral MSSM Higgs bosons.
