In this paper, we study two Higgs doublet models with gauged U(1)_H symmetry, motivated by the excesses around 96 GeV reported by the CMS collaboration in the searches for light resonances decaying to two photons and two \tau's. In this model, one Higgs doublet field is charged under the U(1)_H symmetry to avoid tree-level flavor changing neutral currents. The extra gauge symmetry requires extra chiral fermions, to satisfy the anomaly-free conditions. We analyze the signals of the light resonances, taking into account the contribution of the extra fermions, and discuss the consistency with the experimental results in this model.

Interpreting Light Scalar Excesses and Heavy Scalar Cascades in the $\mu$-Term Extended NMSSM
Viable μNMSSM regions can fit the 95 GeV diphoton/bb anomalies and produce H→hhs and A2→hA1→4b cascades near the 650 and (600,400) GeV CMS structures.

Interpretation of 95 GeV Excess within the Georgi-Machacek Model in Light of Positive Definiteness Constraints
The Georgi-Machacek model keeps viable parameter space for the 95 GeV diphoton and bbbar excesses under positive definiteness constraints, which the paper finds expand the allowed region relative to tree-level bounded...
