论文摘要
我们提出了一种弦理论构建，该构建使我们能够研究两个重夸克的电势，并耦合到浅夸克。在这种情况下，潜力是重夸克之间分离的函数。结果表明，在重型夸克 - 二夸克对称性的小分离处，弦张力的普遍性和分解的普遍性。此外，我们对弦划分距离进行估计。使用我们使用的参数值，发现此距离几乎与重夸克式势能相同。我们还讨论了沉重的夸克夸克潜力及其与Lipkin规则的关系。
We propose a string theory construction which allows us to study properties of the potential of two heavy quarks coupled to a light quark. In such a case, the potential is a function of separation between the heavy quarks. The results show the universality of the string tension and factorization at small separations expected from heavy quark-diquark symmetry. In addition, we make an estimate of the string breaking distance. With the parameter values we use, this distance is found to be almost the same as that for the heavy quark-antiquark potential. We also discuss the heavy quark-quark potential and its relation to Lipkin rule.
