标题： Charmed baryons from lattice QCD

摘要： 最近对含 charm 夸克重子的淬火格点 QCD 模拟结果被呈现出来。 与之前计算相反，发现超精细分裂与夸克模型的预期一致，并且与实验值相当。 使用格点 NRQCD 的初步计算结果与使用 D234 类型的 Dirac-Wilson 动力学对于 charm 夸克得到的结果相容。 显示英文摘要

摘要： The results of a recent quenched lattice QCD simulation for charmed baryons are presented. In contrast to a previous calculation, it is found that hyperfine splittings are in agreement with quark model expectations and comparable to experimental values. Preliminary calculations using lattice NRQCD yield results which are compatible with those obtained using a Dirac-Wilson action of the D234 type for the charm quark.
