复费米子质量项、正则化和CP破坏

Complex fermion mass term, regularization and CP violation

P. Mitra

摘要:

众所周知,QCD的CP破坏θ项可以转化为夸克质量项中的相位。然而,一个含有夸克的复质量项的理论可以被正则化,从而不违反CP,例如通过zeta函数。通过识别对正则化或测度的依赖性来解决矛盾。适当的正则化的选择进行了讨论,并指出了强CP问题的影响。

英文摘要:

It is well known that the CP violating theta term of QCD can be converted to a phase in the quark mass term. However, a theory with a complex mass term for quarks can be regularized so as not to violate CP, for example through a zeta function. The contradiction is resolved through the recognition of a dependence on the regularization or measure. The appropriate choice of regularization is discussed and implications for the strong CP problem are pointed out.
