Interpreting the 95 GeV di-photon and di-tau Excesses in the Georgi-Machacek Model
Qin Chang, Xiaokang Du, Pengxuan Zhu
We revisit the 95~GeV and excesses in the Georgi--Machacek model using a combined fit to a single light -even custodial singlet . Using the one-loop renormalizatio…

Triplet fermion WIMP dark matter in the general supersymmetric Georgi-Machacek model
LiangLiang Shang, Yuanping Wang, Xiaokang Du +2
The supersymmetric custodial triplet model (SCTM), which is a fully-super\-symmetric generalization of the Georgi-Machacek (GM) model, is constructed by extending the Higgs sector…

Interpretation of 95 GeV Excess within the Georgi-Machacek Model in Light of Positive Definiteness Constraints
Xiaokang Du, Huiling Liu, Qin Chang
The recent observation of a di-photon excess around 95 GeV by the CMS and ATLAS Collaborations, along with the excess reported by the LEP Collaboration in the same mass…
