N2 - An electroweak singlet scalar can couple to pairs of vector bosons through loop-induced dimension five operators. Compared to a standard model Higgs boson, the singlet decay widths in the diphotons and Zγ channels are generically enhanced, while decays into massive final states like WW and ZZ are kinematically disfavored. The overall event rates into γγ and Zγ can exceed the standard model expectations by orders of magnitude. Such a singlet may appear as a resonant signal in the γγ and Zγ channels, even with a mass above the WW kinematic threshold.
