The complete AdS_3 x S^3 x T^4 worldsheet S-matrix.

 

Abstract: We derive the non-perturbative worldsheet S matrix for fundamental excitations of Type IIB superstring theory on AdS3S3T4 with Ramond-Ramond  ux. To this end, we study the o-shell symmetry algebra of the theory and its representations.
We use these to determine the S matrix up to scalar factors and we derive the
crossing equations that these scalar factors satisfy. Our treatment automatically
includes fundamental massless excitations, removing a long-standing obstacle in
using integrability to study the AdS3=CFT2 correspondence. The present paper
contains a detailed derivation of results rst announced in arXiv:1403.4543.
