Description
Recently, statistically significant excesses have been observed at the LHC in associated di-photon production (γγ + X) at around 152 GeV in the sidebands of SM Higgs analyses. They are most pronounced in the single-tau, missing-transverse-energy, four-jet and ⩾ 1ℓ+ ⩾ 1b-jet channels and compatible with associated production mechanisms for new Higgs bosons (such as Drell-Yan), leading to a significance of ≈ 4σ.
In this context, I will argue how such excesses can be explained within different new physics scenarios.
