Lifting asymptotic degeneracies with the Mirror TBA (1106.3909v3)
Published 20 Jun 2011 in hep-th
Abstract: We describe a qualitative feature of the AdS_5 x S5 string spectrum which is not captured by the asymptotic Bethe ansatz. This is reflected by an enhanced discrete symmetry in the asymptotic limit, whereby extra energy degeneracy enters the spectrum. We discuss how finite size corrections should lift this degeneracy, through both perturbative (Luscher) and non-perturbative approaches (the Mirror TBA), and illustrate this explicitly on two such asymptotically degenerate states.
