Four-point functions of lowest weight chiral primary operators in N = 4 four-dimensional supersymmetric Yang-Mills theory in the supergravity approximation

We show that the recently found quartic action for the scalars from the massless graviton multiplet of type IIB supergravity compactified on an AdS 53S 5 background coincides with the relevant part of the action of the gauged N58 5D supergravity on AdS5. We then use this action to compute the four-point function of the lowest weight chiral primary operators tr ( f (i f j ) )i nN54 four-dimensional SYM theory at large N and at
