Phys. Rev. D 75, 011901(R) (2007) [5 pages]Chiral transition and mesonic excitations for quarks with thermal massesSee Also: Erratum
We study the effect of a thermal quark mass, mT, on the chiral phase transition and mesonic excitations in the light quark sector at finite temperature in a simple chirally symmetric model. We show that, while nonzero mT lowers the chiral condensate, the chiral transition remains of second order. It is argued that the mesonic excitations have a large decay rate at energies below 2mT, owing to the Landau damping of the quarks and the van Hove singularities of the collective modes. © 2007 The American Physical Society URL:
