Exact Type IIB Superstring Backgrounds

چکیده
We obtain a family of type IIB superstring backgrounds involving RamondRamond fields in ten dimensions starting from a heterotic string background with vanishing gauge fields. To this end the global SL(2, R) symmetry of the type IIB equations of motion is implemented as a solution generating transformation. Using a geometrical analysis we show that the type IIB backgrounds obtained are solutions to all orders in α.

S-Duality and Exact Type IIB Superstring Backgrounds
A geometrical approach in the non-symmetric connection framework is employed to examine the issue of higher order α′ corrections to D=10 type IIB superstring backgrounds with a covariantly constant null Killing isometry and non-zero Ramond-Ramond field content. These describe generalized supersymmetric string waves and were obtained recently by us through the S-duality transformations of purely...
متن کاملK models and type IIB superstring backgrounds.
A family of type IIB superstring backgrounds involving Ramond-Ramond fields are obtained in ten dimensions starting from a K-model through a generalization of our recent results. The unbroken global SL(2, R) symmetry of the type IIB equations of motion are implemented in this context as a solution generating transfromation. A geometrical analysis, based on the tensor structure of the higher ord...
متن کاملOn type II superstrings in bosonic backgrounds: the role of fermions and T-duality
We derive the actions for type II Green-Schwarz strings up to second order in the fermions, for general bosonic backgrounds. We base our work on the so-called normal coordinate expansion. The resulting actions are κ-symmetric and, for the case of surviving background supersymmetries, supersymmetric. We first obtain the type IIa superstring action from the 11D supermembrane by double dimensional...
متن کاملPlane Wave Type II∗ String Backgrounds
In this note we aim to study plane-wave limits of the solutions of type II superstring theories. We consider Freund-Rubin type dS5 ×H5 solutions of type IIB theory and obtain a new kind of plane-wave solutions, we refer them as de Sitter plane-waves or Dpp-waves. Considering Hull’s time-like T-duality we are able to map the Dpp wave solution to maximally supersymmetric Hpp-wave in IIB string th...
