Norms and scalar products for<i>AdS</i><sub>3</sub>
We compute scalar products and norms of Bethe vectors in the massless sector of AdS3 integrable superstring theories, by exploiting the general difference form of the S-matrix of massless excitations in the pure Ramond–Ramond case, and the difference form valid only in the BMN limit in the mixed-flux case. We …
