论文摘要
自发损坏的SU（2）理论是Abelian Higgs模型的最简单概括，其中包含三个同样庞大的载体玻色子和一个单一的Higgs标量。严格的图表证明了该模型在单一规格中的树级单位性，即仅采用物理领域。一种新的病房般的身份用于表明所有振幅的高能量行为不能超过二次。对于所有外壳振幅的生成功能的使用会导致单位性证明。
A spontaneously broken SU(2) theory is the simplest generalization of the Abelian Higgs model, containing three equally massive vector bosons and a single Higgs scalar. A strictly diagrammatic proof is presented of the tree-level unitarity of this model in the unitary gauge, i.e. employing only physical fields. A new Ward-like identity is used to show that the high-energy behaviour of all amplitudes cannot be more than quadratic; the use of generating functions for all off-shell amplitudes then leads to the unitarity proof.
