论文摘要
在上一篇论文\ cite {hatta：2020LTD}中，我们指出了$ cp $ -odd三丝线（Weinberg）操作员与极化深度无弹性散射中的某些扭曲校正之间的连接。基于此观察结果，我们对Weinberg操作员引起的质子和中子的电偶极矩进行数值估计。我们的结果小于基于QCD总规则的先前估计值，约为3个或更多。
In a previous paper \cite{Hatta:2020ltd}, we have pointed out the connection between the $CP$-odd three-gluon (Weinberg) operator and certain twist-four corrections in polarized deep inelastic scattering. Based on this observation, we give a numerical estimate of the electric dipole moment of the proton and neutron induced by the Weinberg operator. Our result is smaller than the previous estimates based on QCD sum rules by a factor of about 3 or more.
