Confinement versus Chiral Symmetry

The phenomenon of color diconfinement when chiral symmetry is restored was illustrated by constructing an effective Lagrangian. For the quarks in the adjoint representation, it was shown that while deconfinement and the chiral transition do not need to coincide, entanglement between them is still present. It was suggested that the confinement is driven by the dynamics of the chiral transition. It was also suggested that if quark masses were very large then chiral symmetry would be badly broken, and could not be used to characterize the phase transition.
