# Fundamental Higgs vs. pseudo-Nambu-Goldstone boson: experimental fingerprints

If we consider the 126 Higgs-like boson as a pseudo-Nambu-Goldstone boson, what are the experimental fingerprints of that case? What are the main differences, in a purely effective field theory approach and/or "new physics" scenario with respect to the fundamental and boring Standard Model Higgs (take it as a neutral singlet, without loss of generality)?

This is an interesting question, I hope we have some phenomenologists who can answer,+1 –  Dilaton Aug 6 '13 at 3:54
Yes, dilaton. It is interesting and puzzling. I guess we should get an enhanced branching ratio to Higgs->Diphoton, since if the higgs is composite or a pseudo-NG boson, it has an enlarged phase-space and it gives more "decay modes". That is my first purely intuitive answer (Of course, in the case you don't know, I am well aware of the "technical" and "analytical" answer to this question). –  riemannium Aug 10 '13 at 12:38
