标题： 4-dimensional spontaneously broken U(1)L gauge theories with a composite Wess-Zumino field

摘要： 一些具有左向费米子耦合的自发对称破缺规范理论，如我们此处提出的阿贝尔模型，可以赋予一个复合标量部分和威斯-祖米诺场；在函数积分形式主义中对它们进行量子化相应地需要引入约束，这些约束与标量对规范对称性的破缺一起，以及其他后果，使希格斯场和费米子（夸克）具有无限质量；这使得它们不可观测。 规范不变性和单位性通过威斯-祖米诺场与费米子流的导数耦合来实现；在上述无限费米子质量极限下，异常得到抵消。 我们展示了如何通过在阶梯近似下重新求和图和重新排列微扰级数，在单环水平上避开可重整化问题，并且由于费米子流是守恒的。 威斯-祖米诺场可以“规范消除”以成为大质量规范场的第三极化；与希格斯粒子紧密相关的赝标量，与威斯-祖米诺场密切相关，表现得像一个阿贝尔介子。 特别是，不需要引入额外的相互作用尺度，这与“技术色理论”不同。 关于轻子部分的问题仅被提及。 显示英文摘要

摘要： Some spontaneously broken gauge theories with left couplings to fermions, like the abelian model that we propose here, can be endowed with a composite scalar sector and Wess-Zumino field ; their quantization in the functionnal integral formalism accordingly requires the introduction of constraints that, together with the breaking of the gauge symmetry by the scalars, and among other consequences, give the Higgs field and the fermions (quarks) infinite masses; this makes them unobservable. Gauge invariance and unitarity are achieved through a derivative coupling of the W-Z field to the fermionic current; the anomaly gets cancelled in the above infinite fermion mass limit. We show how the problems of renormalizability are evaded at the one-loop level by resumming diagrams at the ladder approximation and reshuffling the perturbative series, and because the fermionic current is conserved. The Wess-Zumino field can be "gauged away" to become the 3rd polarization of the massive gauge field; the pseudoscalar partner of the Higgs, tightly linked to the W-Z field, behaves like an abelian pion. In particular, no extra scale of interaction has to be introduced, unlike in "technicolour" theories. Problems concerning the leptonic sector are only mentionned.
