T-Duality , Space-time Spinors and R-R Fields in Curved Backgrounds

  title={T-Duality , Space-time Spinors and R-R Fields in Curved Backgrounds},
  author={Sayed Fawad Hassan},
We obtain the T-duality transformations of space-time spinors (the supersymmetry transformation parameters, gravitinos and dilatinos) of type-II theories in curved backgrounds with an isometry. The transformation of the spinor index is shown to be a consequence of the twist that T-duality introduces between the left and right-moving local Lorentz frames. The result is then used to derive the T-duality action on Ramond-Ramond field strengths and potentials in a simple way. We also discuss the… CONTINUE READING
