摘要:

基于强相互作用费米子,研究了电弱相互作用的动力学对称破缺模型。弱SU(2)的不同表象的类矢量费米子形成对称破缺凝聚,产生轻子和夸克质量。弱规范玻色子的通常标准模型质量是由新费米子场组成的二重态标量场的规范不变有效拉格朗日量得到的。间隙方程推导和找到一个对称性破缺解决方案的条件。模型的参数进一步受到微扰么正性的约束。倾斜的电弱修正对模型的约束很小。结果表明,在下一个对撞机上将产生大量新的带电费米子,并给出了LHC的截面。

英文摘要:

A dynamical symmetry breaking model of electroweak interactions is investigated based on strongly interacting fermions. Vector-like fermions of different representations of the weak SU(2) form a symmetry breaking condensate and generate the lepton and quark masses. The weak gauge bosons get their usual standard model masses from a gauge invariant effective Lagrangian of a doublet scalar field composed of the new fermion fields. Gap equations are derived and the conditions for finding a symmetry breaking solution are presented. The parameters of the model are constrained further by perturbative unitarity. The oblique electroweak corrections only slightly constrain the model. It is shown that the new charged fermions are produced at the next linear colliders in large number and the cross section for the LHC is presented.
