广义熊蜂模型与Lorentz破坏电动力学

Generalized bumblebee models and Lorentz-violating electrodynamics

Michael D. Seifert

摘要:

近年来,通过动力学机制破缺真空中具有非零期望值的张量场的Lorentz对称性一直是重要的研究活动。在这种类型的某些模型中,“洛伦兹破坏场”对这个背景的扰动可以用已知的力来识别。我提出的结果应用这种解释的“广义大黄蜂模型”在以前的工作中发现。在这个模型中,洛伦兹破坏矢量场的扰动可以解释为光子场。然而,这种“大黄蜂光子”的传播速度是方向相关的,不同于常规物质的极限速度,导致可测量的物理效应。这个理论的参数界限可以从共振器实验、加速器物理学和宇宙射线观测中得到。

英文摘要:

The breaking of Lorentz symmetry via a dynamical mechanism, with a tensor field which takes on a non-zero expectation value in vacuum, has been a subject of significant research activity in recent years. In certain models of this type, the perturbations of the "Lorentz-violating field" about this background may be identified with known forces. I present the results of applying this interpretation to the "generalized bumblebee models" found in a prior work. In this model, the perturbations of a Lorentz-violating vector field can be interpreted as a photon field. However, the speed of propagation of this "bumblebee photon" is direction-dependent and differs from the limiting speed of conventional matter, leading to measurable physical effects. Bounds on the parameters of this theory can then be derived from resonator experiments, accelerator physics, and cosmic ray observations.
