Feynman rules for higher-spin gauge fields on AdS

arXiv:1708.08668 · doi:10.1007/JHEP01(2018)060

Abstract

We determine the Feynman rules for the minimal type A higher-spin gauge theory on AdS at cubic order. In particular, we establish the quantum action at cubic order in de Donder gauge, including ghosts. We also give the full de Donder gauge propagators of higher-spin gauge fields and their ghosts. This provides all ingredients needed to quantise the theory at cubic order.
