Quark masses and chiral symmetry
Copyright policy )Quark masses and chiral symmetry
I discuss the global structure of the strongly interacting gauge theory of quarks and gluons as a function of the quark masses and the CP violating parameter $θ$. I concentrate on whether a first order phase transition occurs at $θ=π.$ I show why this is expected when multiple flavors have a small degenerate mass. This transition can be removed by sufficient flavor-breaking. I speculate on the implications of this structure for Wilson's lattice fermions.
