String amplitudes in the Hpp-wave limit of AdS3 × S3
@article{Bianchi2004StringAI, title={String amplitudes in the Hpp-wave limit of AdS3 × S3}, author={Massimo Bianchi and Giuseppe D’Appollonio and Elias Kiritsis and Oswaldo Zapata}, journal={Journal of High Energy Physics}, year={2004}, volume={2004}, pages={074-074} }
We compute string amplitudes on pp-waves supported by NS-NS 3-form fluxes and arising in the Penrose limit of AdS3 × S3 × . We clarify the role of the non-chiral accidental SU(2) symmetry of the background. We comment on the extension of our results to the superstring and propose a holographic formula in the BMN limit of the AdS3/CFT2 correspondence valid for any correlator.
