abstract
Even if the LHC observations are consistent with the Standard model (SM), current LHC results are not precise enough to rule out the presence of new physics. Taking a contrarian view of the SM Higgs fandom, we look out for a more suitable candidate for the 125 GeV boson observed at the LHC. At the same time, a recent result from CMS hints towards an excess near 95 GeV in the diphoton ($\gamma \gamma$) channel. Given these aspects, we revisit the Higgs-radion mixing model to explore the viability of the radion mixed Higgs to be the 125 GeV boson along with the presence of a light radion (to be precise Higgs mixed radion) that can show up in future experiments in the $\gamma \gamma$ channel. We find that the mixed radion-Higgs scenario gives a better fit than the SM, with the radion mixed Higgs as a more suitable 125 GeV scalar candidate. It also gives rise to a diphoton excess from the light radion, consistent with the LHC observations.

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.

Baryon-dark matter coincidence in Randall-Sundrum Model
Graviton- and radion-mediated freeze-in in a Randall-Sundrum model can match the observed dark matter relic abundance, and TeV-scale resonant leptogenesis through the same portals can match the observed baryon asymmet...

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...
