  Article: The big picture

  ABSTRACT: We discuss the conformal field theory and string field theory of the NSR superstring using a BRST operator with a non-minimal term, which allows all bosonic ghost modes to be paired into creation and annihilation operators. Vertex operators for the Neveu-Schwarz and Ramond sectors have the same ghost-number, as do string fields. The kinetic and interaction terms are the same for Neveu-Schwarz as for Ramond string fields, so space-time supersymmetry is closer to being manifest. The kinetic terms and supersymmetry do not mix levels, simplifying component a analysis and gauge fixing.

  Article: Covariant field theory for self-dual strings

  N. Berkovits, W. Siegel
  [show abstract] [hide abstract]
  ABSTRACT: We give a gauge and manifestly SO(2,2) covariant formulation of the field theory of the self-dual string. The string fields are gauge connections that turn the super-Virasoro generators into covariant derivatives.
