没有经典Higgs机制的量子规范模型

Quantum gauge models without classical Higgs mechanism

Michael Duetsch, Jose M. Gracia-Bondia, Florian Scheck, Joseph C. Varilly

摘要:

我们从因果(爱泼斯坦-格拉泽)重整化的观点来考察大质量规范理论的地位,例如那些通常由自发对称性破缺得到的理论。在这个框架中,规范不变性的BRS公式,从有质量(以及无质量)矢量玻色子作为基本实体的正则量子化开始,并进行微扰,允许重新推导相互作用的约化群对称性,规范理论中对标量场的需要,和协变导数。因此,希格斯粒子的存在是解释没有求助于希格斯(-恩格勒-布劳特-古拉尔尼克-哈根-基布尔)机制。一路上,我们消除了对因果规范不变性与大统一理论的兼容性的怀疑。

英文摘要:

We examine the status of massive gauge theories, such as those usually obtained by spontaneous symmetry breakdown, from the viewpoint of causal (Epstein-Glaser) renormalization. The BRS formulation of gauge invariance in this framework, starting from canonical quantization of massive (as well as massless) vector bosons as fundamental entities, and proceeding perturbatively, allows one to rederive the reductive group symmetry of interactions, the need for scalar fields in gauge theory, and the covariant derivative. Thus the presence of higgs particles is explained without recourse to a Higgs(-Englert-Brout-Guralnik-Hagen-Kibble) mechanism. Along the way, we dispel doubts about the compatibility of causal gauge invariance with grand unified theories.
