Abstract: Color Superconductivity at Dense Quark

Matter\ We are interested in the behaviors of the QCD matter at high density but low temperature. Based on the perturbative method, high density QCD matter is expected to be a color superconductor. Color superconducting quark matter can come in a class of different possible phases, when considering different pairing patterns of the quarks. Neutron stars have always provided important information for the cold and dense baryonic matter. We also believe color superconductivity occurs in neutron stars. Moreover, similar as the High Thermal Loop is significant important at high temperature QCD matter, we have calculated the High Density Loop'e2'80'99s distribution in color superconductivity.
