Thermal Color-Superconducting Fluctuations in Dense Quark Matter

Abstract

Thermal fluctuations of the color superconducting order parameter in dense quark matter are investigated in terms of the phenomenological Ginzburg -Landau approach. Our estimates show that fluctuations of the di-quark gap may strongly affect some of thermodynamic quantities even far below and above the critical temperature. If the critical temperature Tc of the di-quark phase transition were rather high ( > ∼ (50 ÷ 70) MeV) one could expect a manifestation of fluctuations of the di-quark gap in the course of heavy ion collisions (above Tc). For Tc ∼ 50 MeV color superconducting fluctuations may also affect an initial stage of the hybrid star evolution.
