On the Dressing Factors, Bethe Equations and Yangian Symmetry of Strings on AdS3 x S3 x T4

Understand

Integrability is believed to underlie the AdS3/CFT2 correspondence with sixteen supercharges.

• We elucidate the role of massless modes within this integrable framework.
• Firstly, we find the dressing factors that enter the massless and mixed-mass worldsheet S matrix.
• Secondly, we derive a set of all-loop Bethe Equations for the closed strings, determine their symmetries and weak-coupling limit.
