Alexandre Arbey, Marco Battaglia, Farvah Mahmoudi

摘要:

寻找重希格斯玻色子玻色子是探索希格斯扇区和探测超对称参数空间的重要步骤。本文在唯象MSSM框架下,讨论了由中性H和A玻色子在LHC上可达的不同衰变通道的边界导出的M(A)和tan β参数的约束。从[M(A)- tan β]平面的覆盖范围方面讨论了目前LHC结果的含义和14 TeV数据的预期灵敏度。新的渠道变得重要,在13和14 TeV的低值tan β的特点是在他们的运动学和重建策略。详细讨论了QCD系统学、超对称环效应和衰变成超对称粒子对这些约束的影响。

英文摘要:

The search for heavy Higgs bosons is an essential step in the exploration of the Higgs sector and in probing the Supersymmetric parameter space. This paper discusses the constraints on the M(A) and tan beta parameters derived from the bounds on the different decay channels of the neutral H and A bosons accessible at the LHC, in the framework of the phenomenological MSSM. The implications from the present LHC results and the expected sensitivity of the 14 TeV data are discussed in terms of the coverage of the [M(A) - tan beta] plane. New channels becoming important at 13 and 14 TeV for low values of tan beta are characterised in terms of their kinematics and the reconstruction strategies. The effect of QCD systematics, SUSY loop effects and decays into pairs of SUSY particles on these constraints are discussed in details.
