从实验数据重建具有弱基纹理零点的夸克质量矩阵

Reconstruction of Quark Mass Matrices with Weak Basis Texture Zeroes from Experimental Input

D. Emmanuel-Costa, C. Simoes

摘要:

所有通过弱基变换得到的具有纹理零点的夸克质量矩阵都与实验数据进行了比较。在弱基中重建了电弱尺度下的夸克质量矩阵M_u和M_d,其中矩阵是厄米矩阵,最多有三个零元。同样的程序也完成了汤川耦合矩阵在大统一尺度的背景下的标准模型和它的最小超对称扩展以及两个Higgs的双重模型。本文还分析了由Froggatt-Nielsen机制自然产生的夸克汤川耦合矩阵上的所有可行的幂结构。

英文摘要:

All quark mass matrices with texture zeroes obtained through weak basis transformations are confronted with the experimental data. The reconstruction of the quark mass matrices M_u and M_d at the electroweak scale is performed in a weak basis where the matrices are Hermitian and have a maximum of three vanishing elements. The same procedure is also accomplished for the Yukawa coupling matrices at the grand unification scale in the context of the Standard Model and its minimal supersymmetric extension as well as of the two Higgs doublet model. The analysis of all viable power structures on the quark Yukawa coupling matrices that could naturally appear from a Froggatt-Nielsen mechanism is also presented.
