Abstract

We calculate the coupling between a vector resonance and two Goldstone bosons in SU(2) gauge theory with N-f = 2 Dirac fermions in the fundamental representation. The considered theory can be used to construct a minimal Composite Higgs models. The coupling is related to the width of the vector resonance and we determine it by simulating the scattering of two Goldstone bosons where the resonance ...
