从流夸克质量到组分夸克质量的动力学过渡的研究

Study of Dynamical Mass of Quarks—From Current Quark to Constituent Quark

摘要: 在彩虹近似下用DysonSchwinger 方程研究了禁闭夸克的传播子, 得到了夸克动力学质量随动量变化的关系, 即得到了从流夸克质量到组分夸克质量的动力学过渡.

Abstract: The quark propagators are studied using the Dyson Schwinger equations in “rainbow” approximation in this article. Quark dynamical masses are obtained, and the mass of constituent quarks used commonly in literature is explained, i.e. the transition from current quark to constituent quark is dynamically given out.
