Lüscher Terms & Limitations of the $AdS_3$ Asymptotic Bethe Ansatz

We recently showed that the Bethe equations for $AdS_3$ integrability describe the spectrum of a much smaller sector than was the case for $AdS_5/CFT_4$. The reason is that wrapping corrections enter much earlier than before, thanks to the presence of massless modes. This explains a mismatch that was seen in one of the classic tests of AdS/CFT integrability, namely the study of circular spinning strings from which Hernandez & Lopez deduced the one-loop dressing phase for AdS5. Several other mismatches may be caused by the same physics.
