Hints for an additional Higgs boson with a mass of about 95 GeV originate from LEP and searches in the diphoton channel by CMS and ATLAS. A search for resonant production of SM plus BSM Higgs bosons in the diphoton plus bb channel by CMS showed some excess for a 650 GeV resonance decaying into the SM Higgs plus a 95 GeV Higgs boson. We investigate whether these phenomena can be interpreted simultaneously within the NMSSM subject to the latest constraints on couplings of the SM Higgs boson, on extra Higgs bosons from the LHC, and on dark matter direct detection cross sections. We find that the hints for a 95 GeV Higgs boson in the diphoton channel by CMS and ATLAS and in the diphoton plus bb channel by CMS can be fitted simultaneously within the 2 sigma level.

The 95 GeV Excess in Models with Two Higgs Doublets plus One Singlet: Model Distinction via Four-top Final States and Triple Higgs Couplings
Using the 95 GeV excess benchmarks, four-top production at HL-LHC and di-Higgs production at ILC500 can distinguish the N2HDM from the 2HDMS for pseudoscalar-mixing angles beyond a computed 'α4 limit'.

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.

Light Scalars in the Extended Georgi-Machacek Model
A global fit of the Georgi-Machacek and extended Georgi-Machacek models finds that the 95 GeV diphoton and bottom-quark excesses are compatible with the 125 GeV Higgs data, while the ditau excess is not, and it sets u...

Deconstructing resonant Higgs pair production at the LHC: effects of coloured and neutral scalars in the NMSSM test case
In the NMSSM, interference between heavy Higgs resonances, SM top loops and stop loops can strongly distort the di-Higgs invariant mass spectrum, and a diagram-by-diagram decomposition makes these distortions interpretable.
