论文摘要
我们提出了一个模型,其中所有费米子都包含在SU(19)仪表对称组的单个不可还原表示中。如果只有一个标量字段,则Yukawa交互由一个数字控制,而不是一个或多个$ 3 \ times3 $耦合矩阵。低能的风味概念完全来自标量扇区参数。更具体地说,标准模型Yukawa矩阵的条目由几个真空期望值控制。
We present a model where all fermions are contained in a single irreducible representation of an SU(19) gauge symmetry group. If there is only one scalar field, Yukawa interactions are controlled by a single number rather than by one or more $3\times3$ matrices of couplings. The low-energy concept of flavor emerges entirely from the scalar-sector parameters; more specifically, entries of the Standard Model Yukawa matrices are controlled by several vacuum expectation values.
