The paper “Protected string spectrum in AdS3/CFT2 from worldsheet integrability“, co-authored by Marco Baggio (KU Leuven, Belgium), Olof Ohlsson Sax (KTH Stockholm), Alessandro Sfondrini (ETH Zurich), Bogdan Stefanski (City University, London), and Alessandro Torrielli, has been accepted for publication in the Journal of High Energy Physics.  In the paper they derive the protected closed-string spectra of AdS3/CFT2 dual pairs with 16 supercharges at arbitrary values of the string tension and of the three-form fluxes. Full details can be found in the final form electronic version which is posted on the arXiV here.
