The model dependence of $m_\varrho / f_\pi$
January 04, 2020
Should a strongly coupled composite Higgs boson scenario be realized in Nature the most easily accessible experimental signal would be new particles made up of the same ingredients as the Higgs but with different quantum numbers. The lightest of these hypothetical new particles would probably be the vector mesons. In this contribution we report results on $m_\varrho / f_\pi$ in the chiral-continuum limit with $SU(3)$ gauge group and $N_f = 2,3,4,5,6$ flavors of fundamental fermions. In addition we compare $m_\varrho / f_\pi$ results from various models with different gauge groups and fermion content. The main conclusion seems to be that the experimental measurement of this vector meson mass will be able to distinguish between gauge groups but less so between the fermion content.
