最小SUSY B-L模型中的双Higgs峰

Double Higgs peak in the minimal SUSY B-L model

W. Abdallah, S. Khalil, S. Moretti

摘要:

出于对在大型强子对撞机的CMS实验记录的$\sim 3σ$过剩的质量顺序$\sim 137$ GeV左右的$ZZ\to 4l$和$γγ$样品,我们分析了第二个中性希格斯玻色子的发现潜力的超对称$B-L$扩展的标准模型(BLSSM)在欧洲核子研究中心的机器。我们证实,在这个框架中,可以产生一个双希格斯峰结构,CP-甚至希格斯玻色子质量在$\sim125$ GeV和$\sim137$ GeV,不同于最小超对称标准模型(MSSM)的情况下。

英文摘要:

Motivated by a $\sim 3σ$ excess recorded by the CMS experiment at the LHC around a mass of order $\sim 137$ GeV in $ZZ\to 4l$ and $γγ$ samples, we analyse the discovery potential of a second neutral Higgs boson in the Supersymmetric $B-L$ extension of the Standard Model (BLSSM) at the CERN machine. We confirm that a double Higgs peak structure can be generated in this framework, with CP-even Higgs boson masses at $\sim125$ GeV and $\sim137$ GeV, unlike the case of the Minimal Supersymmetric Standard Model (MSSM).
