The paper “Boundary Bethe ansatz in massless AdS3“, co-authored by Daniele Bielli (Chulalongkorn University, Thailand), Vasileios Moustakis, and Alessandro Torrielli, has been accepted for publication in the Journal of Physics A: Mathematical and Theoretical. Daniele is a former PhD student at Surrey, and Vasileios is a current PhD student at Surrey. In the paper, they construct the boundary algebraic Bethe Ansatz for the AdS3 X S3 X T4 integrable reflection problem, restricted to the massless sector. A final form preprint is available on Inspire (link here). The screenshot below shows a key result in Section 3.
