Holographic flavor symmetry breaking: from QCD to composite Higgs


As is known that holographic models can produce the QCD meson spectrum. Yet these models assume the flavor symmetry to be conserved, some of the states are thus degenerated. In the first part of this talk, I will show how to break the flavor symmetry in a holographic model in the QCD to get the full meson spectrum. In the second part, we extend this method to a minimal composite Higgs model, the SU(4)/Sp(4)→ SU(2)*SU(2), where the second breaking is implemented by an NJL type of interaction.
