在SU（2）-Higgs模型中计算了所有可用角动量和宇称量子数的能级谱，选择的参数与标准模型中Higgs-W玻色子扇区的实验数据相匹配。观察到几个多玻色子态，有和没有线性动量，都是与弱相互作用的希格斯和W玻色子一致。在这项研究中使用的创造运营商是规范不变的，例如，希格斯算子是二次的，而不是线性的拉格朗日标量场。
The spectrum of energy levels is computed for all available angular momentum and parity quantum numbers in the SU(2)-Higgs model, with parameters chosen to match experimental data from the Higgs-W boson sector of the standard model. Several multi-boson states are observed, with and without linear momentum, and all are consistent with weakly-interacting Higgs and W bosons. The creation operators used in this study are gauge-invariant so, for example, the Higgs operator is quadratic rather than linear in the Lagrangian's scalar field.
