Singlet Scalar Resonances and the Diphoton Excess
ATLAS and CMS recently released the first results of searches for diphoton
resonances in 13 TeV data, revealing a modest excess at an invariant mass of
approximately 750 GeV. We find that it is generically possible that a singlet
scalar resonance is the origin of the excess while avoiding all other
constraints. We highlight some of the implications of this model and how
compatible it is with certain features of the experimental results. In
particular, we find that the very large total width of the excess is difficult
to explain with loop-level decays alone, pointing to other interesting bounds
and signals if this feature of the data persists. Finally we comment on the
robust Z-gamma signature that will always accompany the model we investigate
