Bethe Ansatz for Quantum Strings
Abstract: We propose Bethe equations for the diagonalization of the Hamiltonian of quantum strings on AdS5×S at large string tension and restricted to certain large charge states from a closed su(2) subsector. The ansatz differs from the recently proposed all-loop gauge theory asymptotic Bethe ansatz by additional factorized scattering terms for the local excitations. We also show that our ansa...

متن کاملQuantum Strings and Bethe Equations
Recently there has been a lot of effort to shed more light on the AdS/CFT duality conjecture by using the idea of exact integrability. On the gauge theory side this includes elucidation of integrable properties of the dilatation operator of the planar N = 4 SYM at the leading [1, 2] and higher orders [3] of perturbation theory (see also [4] for earlier account of integrable structures in QCD). ...
متن کاملQuantum corrections to the string Bethe ansatz
One-loop corrections to the energy of semiclassical rotating strings contain both analytic and non-analytic terms in the ’t Hooft coupling. Analytic contributions agree with the prediction from the string Bethe ansatz based on the classical S-matrix, but in order to include non-analytic contributions quantum corrections are required. We find a general expression for the first quantum correction...
متن کاملBethe Ansatz for a Quantum Supercoset Sigma Model
We study an integrable conformal OSp(2m+2|2m) supercoset model as an analog to the AdS5 × S5 superstring world-sheet theory. Using the known S-matrix for this system, we obtain integral equations for states of large particle number in an SU(2) sector, which are exact in the sigma model coupling constant. As a check, we derive as a limit the general classical Bethe equation of Kazakov, Marshakov...
