Abstract
En 中文
We analyze the four-point function of stress-tensor multiplets for the 6d quantum field theory with OSp(8*vertical bar 4) symmetry which is conjectured to be dual to M-theory on AdS(7) x S-4, and deduce the leading correction to the tree-level supergravity prediction by obtaining a solution of the crossing equations in the large-N limit with the superconforrnal partial wave expansion truncated to operators with zero spin. This correction corresponds to the M-theoretic analogue of R-4 corrections in string theory. We also find solutions corresponding to higher-spin truncations, but they are subleading compared to the 1-loop supergravity prediction, which has yet to be calculated.
