Description

In search of beyond standard model, several hints of the presence of a new state at about 95 GeV have recently been observed by both the ATLAS and CMS collaborations based on their full Run 2 data sets. This result becomes particularly intriguing when considering another excess reported by CMS in the di-tau final state at a comparable mass, which exhibits a similar local significance. Moreover, the LEP experiments observed
an excess in the same mass range of a Higgs boson decaying to pairs of a bottom quark and its antiparticle. By combining the two results of the CMS and ATLAS di-photon excesses, we suggest interpreting the three excesses (i.e., in the di-photon, di-tau, and $b\bar{b}$ decay channels) together within the context of a Two-Higgs doublet model extended
by a real Triplet scalar (2HDMrT), with focus on types I and III Yukawa textures. We find that the lightest CP-even Higgs boson in this framework can account for the excess observed in all three channels simultaneously while still being consistent with all other known limits and measurements related to the Higgs sector.
