T-duality of the Green-Schwarz superstring
We study T-duality in the Green-Schwarz formalism to all orders in superspace coordinates. We find two analogs of Buscher rules for the supervielbein and clarify their meaning from the superstring point of view. The transformation rules for the dilaton, spin 1/2 fermions and Ramond-Ramond superfields are also derived. E-mail: [email protected] E-mail: [email protected]
متن کاملLorentz-covariant Green-schwarz Superstring Amplitudes
In a recent paper, the BRST formalism for the gauge-fixed N=2 twistor-string was used to calculate Green-Schwarz supersring scattering amplitudes with an arbitrary number of loops and external massless states. Although the gauge-fixing procedure preserved the worldsheet N=2 superconformal invariance of the twistor-string, it broke the target-space SO(9,1) super-Poincaré invariance down to an SU...
متن کاملGreen-Schwarz formulation of self-dual superstring.
The self-dual superstring has been described previously in a Neveu-SchwarzRamond formulation with local N=2 or 4 world-sheet supersymmetry. We present a Green-Schwarz-type formulation, with manifest spacetime supersymmetry. 1 Work supported by National Science Foundation grant PHY 9211367. Internet address: [email protected].
متن کاملk-ANOMALIES AND SPACE-TIME SUPERSYMMETRY IN THE GREEN-SCHWARZ HETEROTIC SUPERSTRING
The computation of κ-anomalies in the Green-Schwarz heterotic superstring sigmamodel and the corresponding Wess-Zumino consistency condition constitute a powerful alternative approach for the derivation of manifestly supersymmetric string effective actions. With respect to the beta-function approach this technique presents the advantage that a result which is obtained with the computation of be...
متن کاملFiniteness and unitarity of Lorentz covariant Green-Schwarz superstring amplitudes
In two recent papers, a new method was developed for calculating ten-dimensional superstring amplitudes with an arbitrary number of loops and external massless particles, and for expressing them in manifestly Lorentz-invariant form. By explicitly checking for divergences when the Riemann surface degenerates, these amplitudes are proven to be finite. By choosing light-cone moduli for the surface...
