Color Superconductivity and Radius of Quark Star in Extended NJL Model by Using the Dimensional Regularization

High Energy Physics - Phenomenology 2009-11-11 v2

Abstract

A radius of a dense star on the color superconducting phase is investigated in an extended NJL type model with two flavors of quarks. Since the model is non-renormalizable, the results depend on the regularization procedure. Here we apply the dimensional regularization and evaluate the radius of a dense star. Evaluating the TOV equation, we show the relationship between mass and radius of the dense star in the dimensional regularization.
