味$SU(3)^3$自发破缺的夸克Yukawa模型

Quark Yukawa pattern from spontaneous breaking of flavour $SU(3)^3$

Enrico Nardi

摘要:

一个自发破缺夸克味对称性的$SU(3)_Q \times SU(3)_u \times SU(3)_d$不变标量势可以解释标准模型味之谜。作为动力学效应,上下汤川场的真空期望值在味空间中的近似排列结果。所观察到的夸克混合角,弱CP破坏相,和分级夸克质量都可以复制的成本引入额外的(辅助)标量多重态,但不需要引入分级参数。

英文摘要:

A $SU(3)_Q \times SU(3)_u \times SU(3)_d$ invariant scalar potential breaking spontaneously the quark flavour symmetry can explain the standard model flavour puzzle. The approximate alignment in flavour space of the vacuum expectation values of the up and down `Yukawa fields' results as a dynamical effect. The observed quark mixing angles, the weak CP violating phase, and hierarchical quark masses can be all reproduced at the cost of introducing additional (auxiliary) scalar multiplets, but without the need of introducing hierarchical parameters.
