  The Elementary Goldstone Higgs (EGH) model is a perturbative extension of the
standard model (SM), which identifies the EGH boson as the observed Higgs
boson. In this paper, we study pair production of the EGH boson via gluon
fusion at the LHC and find that the resonant contribution of the heavy scalar
is very small and the SM-like triangle diagram contribution is strongly
suppressed. The total production cross section mainly comes from the box
diagram contribution and its value can be significantly enhanced with respect
to the SM prediction.
