光子色散关系会是非线性的吗?
Could the photon dispersion relation be non-linear ?
摘要:
自由光子色散关系是洛伦兹不变性高精度测试的参考量。我们首先概述了可能的洛伦兹不变性违反(LIV)的理论方法。接下来,我们将讨论基于宇宙射线传播的唯象测试,特别是在伽马射线暴(GRB)中。作为一个具体的概念,这可能意味着LIV,然后我们专注于场论在非交换(NC)空间,我们提出了非微扰的结果NC光子的色散关系。
英文摘要:
The free photon dispersion relation is a reference quantity for high precision tests of Lorentz Invariance. We first outline theoretical approaches to a conceivable Lorentz Invariance Violation (LIV). Next we address phenomenological tests based on the propagation of cosmic rays, in particular in Gamma Ray Bursts (GRBs). As a specific concept, which could imply LIV, we then focus on field theory in a non-commutative (NC) space, and we present non-perturbative results for the dispersion relation of the NC photon.
