平直空间中无质量粒子相互作用的新旧禁入定理

Old and New No Go Theorems on Interacting Massless Particles in Flat Space

M. Porrati

摘要:

我们回顾模型独立的参数表明,无质量粒子与重力相互作用在闵可夫斯基背景空间可以有最多的自旋2。这些论点包括温伯格的经典定理,以及温伯格-威滕定理的最近扩展。一个难题所产生的一个明显的反例,这些定理的审查和解决。

英文摘要:

We review model independent arguments showing that massless particles interacting with gravity in a Minkowski background space can have at most spin two. These arguments include a classic theorem due to Weinberg, as well as a more recent extension of the Weinberg-Witten theorem. A puzzle arising from an apparent counterexample to these theorems is examined and resolved.
