探讨Poincaré违背

Probing Poincaré Violation

Rick S. Gupta, Joerg Jaeckel, Michael Spannowsky

摘要:

时空平移不变性,导致能量和动量守恒,不仅是物理学中最基本的,也是最普遍接受的对称性假设。然而,谨慎的做法是将这些假设付诸实验和观察检验。在这篇文章中,我们在这个方向上迈出了第一步,指定了一个简单的周期性的时间依赖,违反了QED的时间平移不变性,并设置唯象约束,除了观测和实验的约束,随时间变化的耦合,我们专注于探测违反能量守恒,如自发产生的光子和电子对和$e \to e γ$过程。我们讨论的时变基本常数的讨论和光玻色暗物质场的情况下,通常也会导致振荡效应的相似性和差异。

英文摘要:

Time and space translation invariance, giving rise to energy and momentum conservation, are not only amongst the most fundamental but also the most generally accepted symmetry assumptions in physics. It is nevertheless prudent to put such assumptions to experimental and observational tests. In this note, we take the first step in this direction, specifying a simple periodic time dependence that violates time translation invariance in QED, and setting phenomenological constraints on it. In addition to observational and experimental constraints on time varying couplings, we focus on probes of violation of energy conservation such as spontaneous production of photon and electron pairs and the $e \to e γ$ process. We discuss similarities and differences to the discussion of time varying fundamental constants and to the case of a light bosonic dark matter field that usually also causes oscillating effects.
