发展新的物理场景的一个主要问题是，参数经常可以调整，以便在微扰理论中几乎可以容纳所有的实验低能结果。因此，需要有额外的限制。现场理论考虑可以对低洼频谱和模型的多样性提供这样的额外约束。特别是对于具有基本或复合希格斯粒子的理论，Fr\ ohlich- morchio - strochi机制提供了一条创造额外条件的途径，尽管要证明它在起作用需要真正的非摄动计算。讨论了这一过程的定性特征，适用于一般的2-希格斯双重态模型、大统一理论和彩色型理论。
One of the major problems in developing new physics scenarios is that very often the parameters can be adjusted such that in perturbation theory almost all experimental low-energy results can be accommodated. It is therefore desirable to have additional constraints. Field-theoretical considerations can provide such additional constraints on the low-lying spectrum and multiplicities of models. Especially for theories with elementary or composite Higgs particle the Fr\"ohlich-Morchio-Strocchi mechanism provides a route to create additional conditions, though showing it to be at work requires genuine non-perturbative calculations. The qualitative features of this procedure are discussed for generic 2-Higgs-doublet models, grand-unified theories, and technicolor-type theories.
