摘要格子量子色动力学提供了含重夸克-粲和底夸克的强子的第一性原理计算。它们的质量谱、衰变率和一些强子矩阵元可以在晶格上以模型无关的方式计算。在这篇综述中，我们介绍了有效的理论，治疗重夸克的晶格。我们总结了重夸克偶素谱的结果，验证了有效理论方法的有效性。然后，我们讨论应用到B物理，这是重夸克的晶格理论的主要目标。本文综述了B介子衰变常数、B参数、半轻子衰变形状因子等重要物理量的晶格计算进展。
▪ Abstract Lattice quantum chromodynamics provides first-principles calculations for hadrons containing heavy quarks—charm and bottom quarks. Their mass spectra, decay rates, and some hadronic matrix elements can be calculated on the lattice in a model-independent manner. In this review, we introduce the effective theories that treat heavy quarks on the lattice. We summarize results on the heavy quarkonium spectrum, which verify the validity of the effective theory approach. We then discuss applications to B physics, which is the main target of the lattice theory of heavy quarks. We review progress in lattice calculations of the B meson decay constant, the B parameter, semileptonic decay form factors, and other important quantities.
