夸克质量矩阵的重整化

Renormalization of the quark mass matrix

S. H. Chiu, T. K. Kuo

摘要:

利用一组重定相不变变量,证明了夸克混合参数的重整化群方程除了在味置换下具有简单的性质外,还可以写成紧凑的形式.我们还发现了这些方程的近似解,如果夸克质量是分级或近简并。

英文摘要:

Using a set of rephasing-invariant variables, it is shown that the renormalization group equations for quark mixing parameters can be written in a form that is compact, in addition to having simple properties under flavor permutation. We also found approximate solutions to these equations if the quark masses are hierarchical or nearly degenerate.
