  The new particle X recently discovered by the ATLAS and CMS Collaborations is
widely expected to have spin zero, but this remains to be determined. The
leading alternative is that X has spin two, presumably with graviton-like
couplings. We show that measurements of the X particle to pairs of vector
bosons constrain such scenarios. In particular, a graviton-like Higgs impostor
in scenarios with a warped extra dimension of AdS type is prima facie excluded,
principally because they predict too small a ratio between the X couplings to
WW and ZZ, compared with that to photons. The data also disfavour universal
couplings to pairs of photons and gluons, which would be predicted in a large
class of graviton-like models.
