95 GeV excess in a CP-violating μ-from-ν SSM

The CMS and ATLAS have recently reported their results searching for light Higgs boson with mass around 95 GeV, based on the full Run 2 data set. In the framework of the CP-violating (CPV) μνSSM, we discuss a ∼ 2.9σ (local) excess at 95 GeV in the light Higgs boson search in the diphoton decay mode as reported by ATLAS and CMS, together with a ∼ 2σ excess (local) in the bb̅ final state at LEP in the same mass range. By introducing CPV phases as well as by mixing CP-even Higgs and CP-odd Higgs, a lighter Higgs boson in the μνSSM can be produced, which can account for the “di-photon excess”.
