Description

We describe a novel regulator of four-dimensional N = 4 Super Yang-Mills theory on a four-sphere. The regulator involves a lift of the theory to a large N matrix model on a non-commutative twistor space. As opposed to other known regulators, this regulator naturally retains both gauge invariance, and the symmetries of the spacetime. We present evidence that in the large N limit, the twistor matrix model correctly reproduces gauge theory scattering amplitudes. We further show that the 1 / N corrections describe an emergent gravitational sector which correctly reproduces tree level scattering amplitudes for Einstein gravity.
