摘要： 我们将薛定谔函数形式应用于确定四费米子算符的重整化群运行，这些算符出现在标准模型有效弱哈密顿量中。 我们的计算使用了威尔逊费米子和算符的奇宇称分量。 对于算符$O_{VA}=(\bar s \gamma_\mu d)(\bar s \gamma_\mu \gamma_5 d)$给出了初步结果。 显示英文摘要

摘要： We apply the Schroedinger Functional (SF) formalism to determine the renormalisation group running of four-fermion operators which appear in the effective weak Hamiltonian of the Standard Model. Our calculations are done using Wilson fermions and the parity-odd components of the operators. Preliminary results are presented for the operator $O_{VA}=(\bar s \gamma_\mu d)(\bar s \gamma_\mu \gamma_5 d)$.
