具有Lorentz破缺质量项的扩展模型的对偶嵌入

Dual embedding of extended models with a Lorentz-breaking mass term

H. G. Fargnoli, L. C. T. Brito, A. P. Baêta Scarpelli, Marcos Sampaio

摘要:

本文研究了具有Lorentz破坏质量项的CPT偶模型。这类模型可能呈现出非常有趣的特征,如超光速传播模式,甚至是瞬时的长程相互作用。在没有洛伦兹对称性的规范-希格斯模型中,在自发规范对称性破缺的情况下,我们研究的质量项可以在经典或量子水平上诱导。通过研究传播子的极点,分析了模型的物理一致性。利用Noether对偶方法,我们得到了该模型的规范不变对偶理论。研究了两种模型之间的物理等价性,得到了两种传播子之间的一般关系。

英文摘要:

In this paper, we investigate a CPT-even model with a Lorentz-violating mass term. Such kind of models may present very interesting features like superluminal modes of propagation or even instantaneous long-range interactions. The mass term we investigate can be induced at classical or quantum level in a scenario with spontaneous gauge symmetry breaking in a gauge-Higgs model without Lorentz symmetry. We analyze the physical consistency of the model by studying the poles of the propagator. By using the Noether Dualization Method (NDM), we obtain a gauge invariant dual theory for this model. The physical equivalence between the two models is investigated and a general relation between the two propagators is obtained.
