Feynman rules for higher-spin gauge fields on AdS$_{d+1}$

Understand

We determine the Feynman rules for the minimal type A higher-spin gauge theory on AdS$_{d+1}$ 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.
