摘要:

虽然LHC的大多数BSM搜索都集中在新的重态上,但NMSSM包含了新的轻态的可能性,这些新的轻态由于它们的单重态性质而逃脱了检测。在这里,我们专注于轻赝标量,调查最近的LHC搜索这样的光状态产生的125 GeV的希格斯玻色子衰变的参数空间的影响。结果表明,虽然直接搜索还不能竞争的要求,125 GeV标量具有SM-样的耦合,搜索触摸允许的参数空间,并应在不久的将来作出现象学的影响。

英文摘要:

While most BSM searches at the LHC focus on heavy new states, the NMSSM contains the possibility of new light states that have escaped detection due to their singlet nature. Here we focus on light pseudoscalars, investigating the parameter space impact of recent LHC searches for such light states stemming from the decay of the 125 GeV Higgs boson. It is shown that, though direct searches can not yet compete with the requirement of the 125 GeV scalar having SM-like couplings, the searches are touching the allowed parameter space and should make a phenomenological impact in the near future.
