Twistor actions for non-self-dual fields ; a new foundation for twistor-string theory

  title={Twistor actions for non-self-dual fields ; a new foundation for twistor-string theory},
  author={Lionel J. Mason},
Twistor space constructions and actions are given for full Yang-Mills and conformal gravity using almost complex structures that are not, in general, integrable. These are used as the basis of a derivation of the twistor-string generating functionals for tree level perturbative scattering amplitudes of Yang-Mills and conformal gravity. The derivation follows by expanding and resumming the classical approximation to the path integral obtained from the twistor action. It provides a basis for… CONTINUE READING
