Explaining the γγ + X excesses at ≈151.5 GeV via the Drell-Yan production of a Higgs triplet

The multi-lepton anomalies suggest the existence of a new scalar with a mass between 145 GeV and 155 GeV, which is compatible with indications of the associated production of a narrow resonance with a mass of ≈151 GeV. These anomalies require a sizable branching fraction of the new scalar to WW. How...
