This mechanism could be related to the gauge symmetry breaking in the SM in the context of SM extensions with very strong interactions, such as technicolor theories. The only model-independent method to study QCD non-perturbatively is lattice QCD.
In this area members of our group have studied the QCD chiral regime via its formulation in a space-time grid. There has been great progress in the possibility of regularizing QCD without breaking the chiral symmetry explicitly, with Ginsparg-Wilson fermions. The QCD chiral regime has been studied from first principles and the connection between the fundamental theory with the effective chiral theory that describes the dynamics of pions and kaons at low energy has been established.
