A New Description of the Superstring

  title={A New Description of the Superstring},
  author={Nathan Berkovits},
This is a review of the new manifestly spacetime-supersymmetric description of the superstring. The new description contains N=2 worldsheet supersymmetry, and is related by a field redefinition to the standard RNS description. It is especially convenient for four-dimensional compactifications since SO(3,1) super-Poincaré invariance can be made manifest. Parts of this work have been done in collaboration with Warren Siegel and Cumrun Vafa.
