Some issues about neutrino processes in color superconducting quark matter
Abstract
Several relevant issues in computing neutrino emissivity in Urca processes in color superconducting quark matter are addressed. These include: (1) The constraint on u quark abundance is given from electric neutrality and the triangle relation among Fermi momenta for participants. (2) The phase space de ned by Fermi momentum reduction of quarks is discussed in QCD and NJL model. (3) Fermi effective model of weak interaction is reviewed with special focus on its form in Nambu-Gorkov basis.
