We introduce a simple framework to estimate the composite Higgs boson coupling to two-photon in technicolor extensions of the standard model. The same framework allows us to predict the composite Higgs to two-gluon process. We compare the decay rates with the standard model ones and show that the corrections are typically of order one. We suggest, therefore, that the two-photon decay process can be used to disentangle a light composite Higgs from the standard model one. We also show that the Tevatron results for the gluon–gluon fusion production of the Higgs either exclude the techniquarks to carry color charges to the 95% confidence level, if the composite Higgs is light, or that the latter must be heavier than around 200 GeV.
