Clover费米子和Iwasaki规范下四个费米子的重整化因子action

Renormalization factor of four fermi operators with clover fermion and Iwasaki gauge action

Yusuke Taniguchi

摘要:

用微扰方法计算了含三叶草项的改进Wilson费米子和岩崎规范作用量下四夸克算符的重整化因子。一个主要的应用应该是$K\toππ$衰减振幅和计算限于奇偶奇算子,其中的运营商是乘法重正化没有混合错误的运营商,具有不同的手征结构。

英文摘要:

Renormalization factors of four-quark operators are perturbatively calculated for the improved Wilson fermion with clover term and the Iwasaki gauge action. A main application shall be the $K\toππ$ decay amplitude and the calculation is restricted to the parity odd operator, for which the operators are multiplicatively renormalizable without mixing with wrong operators that have different chiral structures.
