Light Higgs bosons in the general NMSSM

Understand

Physics beyond the Standard Model (SM) may manifest itself as small deviations from the SM predictions for Higgs signal strengths at 125 GeV.

• Then, a plausible and interesting possibility is that the Higgs sector is extended and at the weak scale there appears an additional Higgs boson weakly coupled to the SM sector.
• Combined with the LEP excess in $e^+e^-\to Z(h\to b\bar b)$, the diphoton excess around 96 GeV recently reported by CMS may suggest such a possibility.
• We examine if those LEP and CMS excesses can be explained simultaneously by a singlet-like Higgs boson in the general next-to-minimal supersymmetric Standard Model (NMSSM).
