格点重夸克-反夸克势与微扰QCD

The heavy quark-antiquark potential from lattice and perturbative QCD

Alexander Laschka, Norbert Kaiser, Wolfram Weise

摘要:

在微扰QCD中,重夸克-反夸克势是不确定的。我们展示了如何推导出一个定义明确且稳定的短程势,它可以与中间距离的格点量子色动力学模拟结果相匹配。讨论了静电势和1/m阶势。

英文摘要:

The heavy quark-antiquark potential in perturbative QCD is subject to ambiguities. We show how to derive a well-defined and stable short-distance potential that can be matched to results from lattice QCD simulations at intermediate distances. The static potential as well as the order 1/m potential are discussed.
