Higgs decay into diphoton in Composite Higgs Model [PDF]
Haiying CaiWe explore the Higgs couplings to gauge bosons in the minimal $SO(5)/SO(4)$ 4D composite Higgs model. The pions scatterings put unitary constraints on the couplings therefore determine the branch ratios of various Higgs decays. Through fine tuning the parameters, enhancement of Higgs to diphoton rate is possible to be achieved with the existence of vector meson fields.View original: http://arxiv.org/abs/1303.3833
