论文摘要
由于尺寸4和尺寸6 Gluonic CP违规，我们介绍了中子电偶极矩的结果，以及使用Clover Valence Quarks在MILC协作产生的HISQ动力学上使用Clover Valence Quarks使用Isovector Quark Chromeclectric偶极矩。对于Gluonic运算符，我们使用梯度流程方案获得无差异连续性结果。对于染色体偶极矩算子，我们使用未流的本地操作员，但讨论如何与伪级操作员进行二次发散混合，可以非扰动地控制。
We present results for the neutron electric dipole moment due to the dimension 4 and dimension 6 gluonic CP violation, and the isovector quark chromoelectric dipole moment using clover valence quarks on HISQ dynamical ensembles generated by the MILC Collaboration. For the gluonic operators, we use the gradient flow scheme to obtain divergence-free continuum results. For the chromoelectric dipole moment operator, we use the unflowed local operator but discuss how the quadratically divergent mixing with the pseudoscalar operator can be controlled nonperturbatively.
