The Bethe Ansatz for AdS5 × S Bound States
نویسنده
چکیده
We reformulate the nested coordinate Bethe ansatz in terms of coproducts of Yangian symmetry generators. This allows us to derive the nested Bethe equations for the bound state string S-matrices. We find that they coincide with the Bethe equations obtained from a fusion procedure. The bound state number dependence in the Bethe equations appears through the parameters x± and the dressing phase only. E-mail: [email protected]

Semiclassical Bethe Ansatz and AdS/CFT
The Bethe ansatz can be used to compute anomalous dimensions in N = 4 SYM theory. The classical solutions of the sigma-model on AdS5 × S 5 can also be parameterized by an integral equation of Bethe type. In this note the relationship between the two Bethe ansätze is reviewed following hep-th/0402207.

متن کاملOn String S-matrix, Bound States and TBA
The study of finite J effects for the light-cone AdS5 × S superstring by means of the Thermodynamic Bethe Ansatz requires an understanding of a companion 2d theory which we call the mirror model. It is obtained from the original string model by the double Wick rotation. The S-matrices describing the scattering of physical excitations in the string and mirror models are related to each other by ...
متن کاملBethe 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 کاملBethe Ansatz from String Sigma Model on S
We derive the asymptotic Bethe ansatz (AFS equations [1]) for the string on S ×R sector of AdS5 ×S5 from the integrable nonhomogeneous dynamical spin chain for the string sigma model proposed in [2]. It is clear from the derivation that AFS equations can be viewed only as an effective model describing a certain regime of a more fundamental inhomogeneous spin chain.
