Gauge Field Fluctuations and First-Order Phase Transition in Color Superconductivity

High Energy Physics - Phenomenology 2009-11-10 v3 Superconductivity Nuclear Theory

Abstract

We study the gauge field fluctuations in dense quark matter and determine the temperature of the induced first-order phase transition to the color-superconducting phase in weak coupling. We find that the local approximation of the coupling between the gauge potential and the order parameter, employed in the Ginzburg-Landau theory, has to be modified by restoring the full momentum dependence of the polarization function of gluons in the superconducting phase.
