Query: A next-to-leading Luescher formula   We propose a next-to-leading Luescher-like formula for the finite-size
corrections of the excited states energies in integrable theories. We
conjecture the expressions of the corrections for both the energy and the
particles' rapidities by interpreting the excited states as momenta-dependent
defects. We check the resulting formulas in some simple relativistic model and
conjecture those for the AdS5/CFT4 case.
