A Representation of Symmetry Generators for the Type IIB Superstring on a Plane Wave in the U(4) Formalism

نویسنده

چکیده

We calculate the symmetry currents for the type IIB superstring on a maximally supersymmetric plane wave background using the N=(2,2) superconformally covariant U(4) formulation developed by Berkovits, Maldacena and Maoz. An explicit realization of the U(4) generators together with 16 fermionic generators is obtained in terms of the N=(2,2) worldsheet fields. Because the action is no longer quadratic, we use a light-cone version to display the currents in terms of the covariant worldsheet variables.

Type IIB Green-Schwarz superstring in plane wave Ramond-Ramond background

We construct the covariant κ-symmetric superstring action for type IIB superstring on plane wave space supported by Ramond-Ramond background. The action is defined as a 2d sigma-model on the coset superspace. We fix the fermionic and bosonic light-cone gauges in the covariant Green-Schwarz superstring action and find the light-cone string Lagrangian and the Hamiltonian. The resulting light-cone...

N=2 Superconformal Description of Superstring in Ramond-ramond Plane Wave Backgrounds

Using the U(4) formalism developed ten years ago, the worldsheet action for the super-string in Ramond-Ramond plane wave backgrounds is expressed in a manifestly N=(2,2) superconformally invariant manner. This simplifies the construction of consistent Ramond-Ramond plane wave backgrounds and eliminates the problems associated with light-cone interaction point operators. Although the constructio...

Superstring in the plane-wave background with RR flux as a conformal field theory

We study the type IIB superstring in the plane-wave background with RamondRamond flux and formulate it as an exact conformal field theory in operator formalism. One of the characteristic features of the superstring in a consistent background with RR flux, such as the AdS5×S and its plane-wave limit, is that the leftand the right-moving degrees of freedom on the worldsheet are inherently coupled...

N = 2 Sigma Models for Ramond - Ramond Backgrounds

Using the U(4) hybrid formalism, manifestly N=(2,2) worldsheet supersymmetric sigma models are constructed for the Type IIB superstring in Ramond-Ramond backgrounds. The Kahler potential in these N=2 sigma models depends on four chiral and antichiral bosonic superfields and two chiral and antichiral fermionic superfields. When the Kahler potential is quadratic, the model is a free conformal fie...
