有限T下经典格点规范理论中的本征静电势

Proper static potential in classical lattice gauge theory at finite T

Alexander Lehmann, Alexander Rothkopf

摘要:

在经典格点规范理论中计算了有限温度下静态夸克与反夸克之间的真实时相互作用势。我们的中心结果是确定的屏蔽实部的潜力,我们再次确认存在的虚部。实部与静态源对规范场的反作用密切相关,通过高斯定律合并。讨论了量子和经典格点规范理论中静态源处理的不同之处。

英文摘要:

We compute the proper real-time interaction potential between a static quark and antiquark in classical lattice gauge theory at finite temperature. Our central result is the determination of the screened real-part of this potential, and we reconfirm the presence of an imaginary part. The real part is intimately related to the back-reaction of the static sources onto the gauge fields, incorporated via Gauss's law. Differences in the treatment of static sources in quantum and classical lattice gauge theory are discussed.
