可能的96 GeV过量的N2HDM解决方案

An N2HDM Solution for the possible 96 GeV Excess

T. Biekötter, M. Chakraborti, S. Heinemeyer

摘要:

我们讨论了CMS报道的~96 GeV双光子衰变模式下轻希格斯玻色子搜索中的~3 σ信号(局部),以及在LEP的bb末态中相同质量范围内的~2 σ过剩(局部)。我们回顾了在2~Higgs双重态模型中,这个可能的信号作为一个希格斯玻色子玻色子的解释。结果表明,N2 HDM中最轻的希格斯玻色子玻色子可以同时完美地拟合这两个超数,而完整的希格斯玻色子扇区符合所有的希格斯玻色子测量和排斥边界以及其他理论和实验约束.研究表明,特别是N2 HDM ~II型,可以最好地拟合数据,从而得到超对称解释。在这方面,NMSSM和munuSSM的简要回顾。

英文摘要:

We discuss a ~3 sigma signal (local) in the light Higgs-boson search in the diphoton decay mode at ~96 GeV as reported by CMS, together with a ~2 sigma excess (local) in the bb final state at LEP in the same mass range. We review the interpretation of this possible signal as a Higgs boson in the 2~Higgs Doublet Model with an additional real Higgs singlet (N2HDM). It is shown that the lightest Higgs boson of the N2HDM can perfectly fit both excesses simultaneously, while the full Higgs-boson sector is in agreement with all Higgs-boson measurements and exclusion bounds as well as other theoretical and experimental constraints. It is demonstrated that in particular the N2HDM type~II and can fit the data best, leading to a supersymmetric interpretation. The NMSSM and the munuSSM are briefly reviewed in this respect.
