Query: A 750 GeV graviton and the Higgs as a pNGB   We study the diphoton excess at 750 GeV reported by ATLAS and CMS, by
assuming that it corresponds to a new spin-two resonant state. We model this
state as a massive graviton in a two-site model. We show that the very
stringent bounds from $VV$ final states can be evaded naturally by considering
that the Higgs is a pseudo Nambu-Goldstone boson. In this case the couplings of
the graviton to the longitudinal electroweak gauge bosons can be parametrically
suppressed. On the other hand, partial compositeness allows to suppress the
leptonic channels. We compute loop-induced contributions to the graviton
couplings by the presence of the SM third generation of quarks and composite
partners of the SM fermions and obtain that they are not important. We find
that the diphoton signal and the experimental constraints from other decay
channels can be reproduced in a large and natural region of the parameter space
of the theory.
