尽管相互作用较弱，但 QED 可以支持束缚态。原则上，希格斯区域的弱相互作用也是如此。事实上，很久以前就有人争论说，在这个区域中，束缚态和基本粒子之间应该存在对偶性，至少在希格斯凝聚体的膨胀中是这样的。使用晶格模拟研究了这是否在领先顺序之外仍然成立，并找到了支持。这提供了将横截面中的峰自然地解释为束缚态。毫无疑问，这意味着标准模型中希格斯以及 W 和 Z 束缚态存在（可能非常广泛）共振。
Though being weakly interacting, QED can support bound states. In principle, this can be expected for the weak interactions in the Higgs sector as well. In fact, it has been argued long ago that there should be a duality between bound states and the elementary particles in this sector, at least in leading order in an expansion in the Higgs condensate. Whether this remains true beyond the leading order is investigated using lattice simulations, and support is found. This provides a natural interpretation of peaks in cross sections as bound states. Unambiguously, this would imply the existence of (possibly very broad) resonances of Higgs and W and Z bound states within the standard model.
