On solvable models of type IIB superstring in NS-NS and R-R plane wave backgrounds
We consider type IIB string in the two plane-wave backgrounds which may be interpreted as special limits of the AdS3 × S supported by the NS-NS or R-R 3-form backgrounds. The NS-NS plane-wave string model is equivalent to a direct generalization of the NappiWitten model, with its spectrum being similar to that of strings in constant magnetic field. The R-R model can be solved in the light-cone ...
متن کاملType IIB Orientifolds with NS-NS Antisymmetric Tensor Backgrounds
We consider six dimensional N = 1 space-time supersymmetric Type IIB orientifolds with non-zero untwisted NS-NS sector B-field. The B-field is quantized due to the requirement that the Type IIB spectrum be left-right symmetric. The presence of the B-field results in rank reduction of both 99 and 55 open string sector gauge groups. We point out that in some of the models with non-zero B-field th...
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 کاملDilatonic Parallelizable NS-NS Backgrounds
We complete the classification of parallelizable NS-NS backgrounds in type II super-gravity by adding the dilatonic case to the result of Figueroa-O'Farrill on the non-dilatonic case. We also study the supersymmetry of these parallelizable backgrounds. It is shown that all the dilatonic parallelizable backgrounds have sixteen supersymmetries. The parallelizable pp-wave backgrounds have been rec...
متن کاملExact Type IIB Superstring Backgrounds
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 solution...
