论文摘要
核子和核的电偶极力矩（EDM）被积极地视为CP违规的直接证据。需要计算晶格上的核子EDM，以连接QCD中违反QCD相互作用或其他CP违反标准模型以外的新物理源的CP相互作用的CP的有效CP。其中，Theta诱导的Nucleon EDM是唯一的可重差异相互作用，已广泛研究在晶格上。在报告中，我们回顾了核子EDM诱导QCD Theta项的晶格计算的最新发展。
Electric dipole moments (EDMs) of nucleons and nuclei are actively considered as direct evidence of the CP violation. Calculations of nucleon EDMs on lattice are required to connect the quark- and hadron- level effective CP violating interactions within QCD or other CP violating sources in new physics beyond the standard model. Among them, the theta-induced nucleon EDM, that is the only such renormalizable interaction, has widely been investigated on a lattice. In the report, we review recent developments of the lattice calculations of nucleon EDM induced QCD theta term.
