In this talk I consider loop integrands for correlators of “master” operators in N=4 SYM.  Loop integrands are Born-level correlators in the self-dual sector
of N = 4 SYM, while master operators are determinant operators which serve as generating functions of all single-trace half-BPS operators. 
Working in twistor space and using matrix duality I will reformulate these integrands in terms of a matrix integral which also manifests a
10 dimensional structure that combines spacetime and R-charge symmetries.

This talk is based on work in progress with S. Caron-Huot and F. Coronado.
