Abstract: We study real-time correlators in the warped AdS-CFT correspondence. We applythe prescription used in the usual AdS-CFT correspondence and obtain theretarded Green-s functions for the scalar and vector fields in the spacelikewarped and the null warped black hole backgrounds. We find that the retardedGreen-s functions and the cross sections are well consistent with thepredictions from dual CFT. Our results not only support strongly theconjectured warped AdS-CFT correspondence, but also show that the usualrelativistic AdS-CFT prescription of obtaining the real-time correlators remaineffective in more general backgrounds with anisotropic conformal infinity.
