摘要

在有效的NJL模型框架内得到的相结构对正则化方案和拟合的依赖性是众所周知的。本文表明，在不同的正则化方案下，具有同位旋和手性不平衡的致密夸克物质的相结构具有很好的精度。例如，最近预测了具有手性不平衡的稠密夸克物质中的介子凝聚及其对高重子密度下主要存在的彩色超导现象的弹性。

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.
