Finite temperature Mott transition in a nonlocal PNJL model

We provide a novel calculation of the Mott effect in non-local PNJL models. We find that the “deconfinement” transition temperature in these models is lower than the Mott temperature. Furthermore, the mass and the width of the pi and the sigma meson modes is calculated with the result that the width in nonlocal models is in general reduced as compared to local models. Difficulties encountered while attempting to “Wick rotate” covariant models are carefully discussed.
