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.

  1. Soft mode dynamics associated with QCD critical point and color superconductivity -- pseudogap, anomalous dilepton production and electric conductivity

    hep-ph 2026-04 unverdicted novelty 5.0

    Soft modes tied to the QCD critical point and color superconductivity create a pseudogap in quark spectra and boost electric conductivity plus dilepton production above the transition temperatures.
