A googly amplitude from the Bmodel in twistor space
Abstract
Recently it has been proposed that gluon scattering amplitudes in gauge theory can be computed from the Dinstanton expansion of the topological Bmodel on Bbb P^{34}, although only maximally helicity violating (MHV) amplitudes have so far been obtained from a direct Bmodel calculation. In this note we compute the simplest nonMHV gluon amplitudes (+ +    and +  +  ) from the Bmodel as an integral over the moduli space of degree 2 curves in Bbb P^{34} and find perfect agreement with YangMills theory.
