Possibility of Spontaneous Parity Violation in Hot QCD
Possibility of Spontaneous Parity Violation in Hot QCD
We suggest that for QCD in the limit of a large number of colors, N, the axial U(1) symmetry of massless quarks is effectively restored at the deconfining=chiral phase transition. If the deconfining transition is of second order, then the chiral transition is weakly first order. In this case, metastable …
