标题： Heavy quarks, gluons and the confinement potential in Coulomb gauge

摘要： 我们考虑库仑规范QCD的重夸克极限，其中将杨-米尔斯部分截断为仅包含（修饰的）两点函数。 我们发现间隙方程和Bethe-Salpeter方程的rainbow-ladder近似是非微扰精确的，并且我们提供了时间胶子传播子与夸克禁闭势之间的直接联系。 此外，我们表明只有颜色单态夸克-反夸克（介子）和夸克-夸克（SU(2)重子）束缚态是物理上允许的。 显示英文摘要

摘要： We consider the heavy quark limit of Coulomb gauge QCD, with the truncation of the Yang-Mills sector to include only (dressed) two-point functions. We find that the rainbow-ladder approximation to the gap and Bethe-Salpeter equations is nonperturbatively exact and moreover, we provide a direct connection between the temporal gluon propagator and the quark confinement potential. Further, we show that only bound states of color singlet quark-antiquark (meson) and quark-quark (SU(2) baryon) pairs are physically allowed.
