Heterotic twistor-string theory

Abstract:

We reformulate twistor-string theory as a heterotic string based on a twisted (0, 2) model. The path integral localizes on holomorphic maps, while the (0, 2) moduli naturally correspond to the states of N = 4 super-Yang-Mills and conformal supergravity under the Penrose transform. We show how the standard twistor-string formulae of scattering amplitudes as integrals over the space of curves in supertwistor space may be obtained from our model. The corresponding string field theory gives rise ...
