Higher spins in AdS and twistorial holography

In this paper we simplify and extend previous work on three-point functions in Vasiliev's higher spin gauge theory in AdS(4). We work in a gauge in which the space-time dependence of Vasiliev's master fields is gauged away completely, leaving only the internal twistor-like variables. The correlation functions of boundary operators can be easily computed in this gauge. We find complete agreement of the tree level three point functions of higher spin currents in Vasiliev's theory with the conjectured dual free O(N) vector theory.
