Recently Lunin and Maldacena used an SL(3, R) transformation of theAdS5×S background to generate a supergravity solution dual to a so-called β-deformation of N = 4 super Yang-Mills theory. We use a T-duality-shift-T-duality (TsT) transformation to obtain the β-deformed background for real β ≡ γ, and show that solutions of string theory equations of motion(More)
We compute 1-loop correction E1 to the energy of folded string in AdS5 ×S5 (carrying spin S in AdS5 and momentum J in S ) using “long string” approximation in which S ≫ J ≫ 1. According to AdS/CFT E1 should represent first subleading correction to strong coupling expansion of anomalous dimension of higher twist SL(2) sector operators TrDSZJ . We show that(More)
We review the recent advances towards finding the spectrum of the AdS5 × S superstring. We thoroughly explain the theoretical techniques which should be useful for the ultimate solution of the spectral problem. In certain cases our exposition is original and cannot be found in the existing literature. The present Part I deals with foundations of classical(More)
We analyze the psu(2, 2|4) supersymmetry algebra of a superstring propagating in the AdS5 × S background in the uniform light-cone gauge. We consider the off-shell theory by relaxing the level-matching condition and take the limit of infinite light-cone momentum, which decompactifies the string world-sheet. We focus on the psu(2|2) ⊕ psu(2|2) subalgebra(More)
We present a detailed analysis of the 4-point functions of the lowest weight chiral primary operators O ∼ trφφ in N = 4 SYM4 at strong coupling and show that their structure is compatible with the predictions of AdS/CFT correspondence. In particular, all powersingular terms in the 4-point functions exactly coincide with the contributions coming from the(More)
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(More)
