Superstrings on AdS 5 × S 5 supertwistor space

چکیده
We derive the Green-Schwarz action on AdS 5 × S 5 using an alternate version of the coset superspace construction. By Wick rotations and Lie algebra identifications we bring the coset to GL(4|4)/(Sp(4) ⊗ GL(1)) 2 , which allows us to represent the conformal transformations on unconstrained matrices. The derivation is more streamlined even for the bosonic sector, and conformal symmetry is manifest at every step. κ-symmetry gauge fixing is more transparent.

متن کاملThe Algebraic Curve of Classical Superstrings on AdS 5 × S 5
We investigate the monodromy of the Lax connection for classical IIB superstrings on AdS 5 × S 5. For any solution of the equations of motion we derive a spectral curve of degree 4 + 4. The curve consists purely of conserved quantities, all gauge degrees of freedom have been eliminated in this form. The most relevant quantities of the solution, such as its energy, can be expressed through certa...

The isometries of AdS 5 space and supersymmetric AdS 5 ⊗ S 1 space are non-linearly realized on four dimensional Minkowski space. The resultant effective actions in terms of the Nambu-Goldstone modes are constructed. The dilatonic mode governing the motion of the Minkowski space probe brane into the co-volume of supersymmetric AdS 5 space is found to be unstable and the bulk of the AdS 5 space ...
متن کاملSingletons and Logarithmic Cft in Ads/cft Correspondence
We discuss a possible relation between singletons in AdS space and logarithmic conformal field theories at the boundary of AdS. It is shown that the bulk Lagrangian for singleton field (singleton dipole) induces on the boundary the two-point correlation function for logarithmic pair. Bulk interpretation of mixing between logarithmic operator D and zero mode operator C under the scale transforma...
متن کاملTopological Gauge Theory and Twistors
By use of harmonic superfields, Witten’s topological gauge theory is written as a field theory on a supertwistor space. Further, using the realisation of complex compactified Minkowski space as a quadric in CP , we show that the theory has a simple formulation in terms of analytic superfields on super-CP 5 ×CP . This research was supported in part by the U.S. Department of Energy
