摘要: The spectrum of the light-cone AdS5×S5 superstring contains states composed particles with complex momenta including in particular those which turn into bound decompactification limit. We propose mirror TBA description for these states. focus on a three-particle state is finite-size representative scattering fundamental particle and two-particle dual to an operator from $ \mathfrak{s}\mathfrak{u}(2) $ sector \mathcal{N} = 4\;{\text{SYM}} . find that analytic behavior Y-functions differs drastically case real momenta. Most importantly, Y Q -functions exhibit poles analyticity strip leads appearance new terms formula energy this state. In addition, equations are supplied by quantization conditions involve 2. Considering yet another example three- state, we corresponding do not even 1. Our treatment can be generalized wide class
