dc.description.abstractWe discuss the possibility of interpreting the recent experimental hints in favor of a 95 GeV resonance with extensions of the Standard Model featuring an extra Higgs doublet and SM scalar (2HDM+s) or pseudoscalar singlet (2HDM+a). We compare the possibility of reproducing the experimental anomalies with the theoretical constraints on the extended Higgs sector as well as complementary bounds coming from flavor physics and other colliders searchers. For both the 2HDM+s and 2HDM+a we will consider a generic natural flavor conserving (NFC) model as well as the customary type-I, -II, -X and -Y configurations of the Yukawa coupling to the BSM Higgs bosons. We find that no model is able to reproduce all experimental hints, and plot the 2σ C.L. favored regions in the parameter space.en
