Pion Condensation and Color Superconductivity: Different Regularization Schemes

The dependence of the phase structure obtained in the framework of effective NJL model on regularization scheme and fit used is rather well known. It has been shown in this letter that with good precision the phase structure of dense quark matter with isospin and chiral imbalances are the same for different regularization schemes. For example, recent prediction of pion condensation in dense quark matter with chiral imbalance and its resilience against color superconductivity phenomenon, which is dominant at high baryon densities.
