众所周知，在TeV尺度下，类QCD强动力学破坏了电弱对称性的Technicolor模型通常会对低能观测值进行不可接受的大修正。我们研究了由强动力学引起的电弱对称性破缺模型，其中规范对称性被扩展到包括任意数量的附加SU（2）和U（1）因子。这类模型包括最近提出的五维“无希格斯玻色子”情景的解构版本。我们的结论是，在这些理论中存在的附加结构不抑制强耦合的短距离物理的影响，精密的电弱观测。特别是，对称性破缺是由于类QCD动力学的可能性仍然强烈不赞成的数据。
It is well known that technicolor models in which the electroweak symmetry is broken by QCD-like strong dynamics at the TeV scale generally predict unacceptably large corrections to low-energy observables. We investigate the models of electroweak symmetry breaking by strong dynamics in which the gauge symmetry is extended to include an arbitrary number of additional SU(2) and U(1) factors. This class of models includes the deconstructed version of the recently proposed five-dimensional ``Higgsless'' scenario. We conclude that the additional structure present in these theories does not suppress the effects of strongly coupled short-distance physics on the precision electroweak observables. In particular, the possibility that the symmetry breaking is due to QCD-like dynamics is still strongly disfavored by data.
