在这封信中,重正化群方程的(味道保存)CP破坏相互作用推导到六维,包括所有的四夸克运营商,在一个循环的水平。我们将它们应用到中性标量玻色子和色八重态标量玻色子与夸克具有CP破坏的Yukawa相互作用的模型中,并讨论了这些模型中的中子电偶极矩。
In this Letter, the renormalization-group equations for the (flavor-conserving) CP-violating interaction are derived up to the dimension six, including all the four-quark operators, at one-loop level. We apply them to the models with the neutral scalar boson or the color-octet scalar boson which have CP-violating Yukawa interactions with quarks, and discuss the neutron electric dipole moment in these models.
