我们利用相对论重夸克作用研究了先前在332 × 64晶格上生成的2+1风味PACS-CS构型的粲重子质谱。动态上下夸克质量和奇异夸克质量被调整到它们的物理值，从那些在组态生成中使用的重加权。在物理点上，由重子质量确定的逆晶格间距为1 = 2.194(10)GeV，因此空间范围为L = 32a = 2.88(1) fm。我们对粲重子质量的计算结果与实验值一致
We investigate the charmed baryon mass spectrum using the relativistic heavy quark action on 2+1 flavor PACS-CS configurations previously generated on 32 3 × 64 lattice. The dynamical updown and strange quark masses are tuned to their physical values, reweighted from those employed in the configuration generation. At the physical point, the inverse lattice spacing determined from the baryon mass gives a 1 = 2.194(10) GeV, and thus the spatial extent becomes L = 32a = 2.88(1) fm. Our results for the charmed baryon masses are consistent with experimental values, �
