Relativistic limit on the AdS3 × S3 × S3 × S1 string worldsheet
摘要
We study the relativistic limit of the worldsheet S-matrix of AdS3 × S3 × S3 × S1 strings in the presence of mixed Ramond-Ramond (RR) and Neveu-Schwarz-Neveu-Schwarz (NS-NS) flux and complete the S-matrix bootstrap including the dressing factors for fundamental particles and bound states. Our results agree with the relativistic limit of the recent proposal arXiv:2512.07721.
