我们研究了SU(2) × U(1)场景的一些现象学方面，其中属于SU(2)的任意表示的标量涉及电弱对称性破缺。由此推导出相互作用项。从纵向规范玻色子散射的树级统一性要求出发，对任意标量扇区进行了约束。我们还证明了ρ参数对一般结构的约束与顶点精确测量的约束之间存在显著的互补性。最后，讨论了e+e−碰撞中产生此类希格斯玻色子的一些显著特征。
We have investigated some phenomenological aspects of an SU(2) × U(1) scenario where scalars belonging to arbitrary representations of SU(2) are involved in electroweak symmetry breaking. The resulting interaction terms are derived. Some constraints are obtained on the arbitrary scalar sector from the requirement of tree-level unitarity in longitudinal gauge boson scattering. We also show that there is a remarkable complimentarity between the constraints on a general structure from the ρ parameter and those from precision measurement of the vertex. Finally, some salient features about the production of such Higgs bosons in e+e− collision are discussed.
