Double Higgs peak in the minimal SUSY B-L model

TL;DR

This paper explores the potential to observe a second Higgs boson around 137 GeV in the SUSY B-L model, motivated by CMS excess, showing a double peak structure not present in the MSSM.

Contribution

It demonstrates that the SUSY B-L model can naturally produce a double Higgs peak with masses near 125 GeV and 137 GeV, unlike the MSSM.

Findings

Double Higgs peak structure possible in the BLSSM.

Masses at approximately 125 GeV and 137 GeV.

Potential explanation for CMS excess.

Abstract

Motivated by a $\sim 3\sigma$ excess recorded by the CMS experiment at the LHC around a mass of order $\sim 137$ GeV in $ZZ\to 4l$ and $\gamma\gamma$ 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).
