Universal Limits on Massless High-Spin Particles
arXiv:0804.4672 · doi:10.1103/PhysRevD.78.065016
Abstract
We present a model-independent argument showing that massless particles interacting with gravity in a Minkowski background space can have at most spin two. This result is proven by extending a famous theorem due to Weinberg and Witten to theories that do not possess a gauge-invariant stress-energy tensor.
