标题： More on Screening and Confinement in 2D QCD

摘要： 我们通过以下三种方式进一步证明了无质量SU(\$N_c\$)玻色化QCD的屏蔽行为：(i) 计算外部夸克之间的势能，(ii) 也对外部源进行玻色化并分析组合系统的态，以及(iii) 使用\$N_f\$（味的数量）展开。 我们写下新的“非阿贝尔施温格类似”运动方程解，计算它们的质量，并论证这种类型的重模交换与屏蔽机制相关。 利用(ii)和(iii)，我们展示了具有大质量动力学费米子的禁闭现象。 我们通过对标量流电流应用点分裂方法，展示了\$N=1\$超杨-米尔斯理论的屏蔽行为。 显示英文摘要

摘要： We provide further evidence for the screening behavior of massless SU(N_c) bosonized QCD by (i) computing the potential between external quarks, (ii) bosonizing also the external sources and analyzing the states of the combined system and (iii) using an expansion in N_f- the number of flavors. We write down novel "non-abelian Schwinger like" solutions of the equations of motion, compute their masses and argue that an exchange of massive modes of this type is associated with the screening mechanism. Confinement for massive dynamical fermions is shown using (ii) and (iii). We show the screening behavior of the N=1 super Yang Mills theory, by applying a point splitting method to the scalar current.
