λ-deformation of the AdS5 × S5 pure spinor superstring
Abstract The lambda deformation of the pure spinor formalism of the superstring in the AdS 5 × S 5 background is introduced. It is shown that the deformation preserves the integrability as well
Generalized IIB supergravity from exceptional field theory
A bstractThe background underlying the η-deformed AdS5 × S5 sigma-model is known to satisfy a generalization of the IIB supergravity equations. Their solutions are related by T-duality to solutions
Exploring the lambda model of the hybrid superstring
A bstractThe purpose of this contribution is to initiate the study of integrable deformations for different superstring theory formalisms that manifest the property of (classical) integrability. In
Embeddings of integrable models in supergravity and their perturbative stability
We discuss the perturbative stability of an AdS 3 non-supersymmetric solution of the type-IIB supergravity, whose internal geometry is given by the direct product of a round three-sphere and two
Target space supergeometry of η and λ-deformed strings
A bstractWe study the integrable η and λ-deformations of supercoset string sigma models, the basic example being the deformation of the AdS5 × S5 superstring. We prove that the kappa symmetry
On the dressing factors, Bethe equations and Yangian symmetry of strings on AdS3 × S3 × T4
Integrability is believed to underlie the AdS3/CFT2 correspondence with sixteen supercharges. We elucidate the role of massless modes within this integrable framework. Firstly, we find the dressing
Classical and quantum aspects of Yang-Baxter Wess-Zumino models
A bstractWe investigate the integrable Yang-Baxter deformation of the 2d Principal Chiral Model with a Wess-Zumino term. For arbitrary groups, the one-loop β-functions are calculated and display a
Analytic integrability for strings on η and λ deformed backgrounds
A bstractIn this paper, based on simple analytic techniques, we explore the integrability conditions for classical stringy configurations defined over η as well as λ-deformed backgrounds. We perform
Separation of variables in the WZW models
We consider dynamics of scalar and vector fields on gravitational backgrounds of the Wess–Zumino–Witten models. For SO(4) and its cosets, we demonstrate full separation of variables for all fields
Integrable asymmetric λ-deformations
A bstractWe construct integrable deformations of the λ-type for asymmetrically gauged WZW models. This is achieved by a modification of the Sfetsos gauging procedure to account for a possible


The complete AdS 3 × S 3 × T 4 worldsheet S-matrix
We derive the non-perturbative worldsheet S matrix for fundamental excitations of Type IIB superstring theory on AdS3×S×T with Ramond-Ramond flux. To this end, we study the off-shell symmetry algebra
Hidden Symmetries of the AdS_5 x S^5 Superstring
Attempts to solve Yang-Mills theory must eventually face the problem of analyzing the theory at intermediate values of the coupling constant. In this regime neither perturbation theory nor the
Integrable deformation of the AdS5×S5 superstring action.
An integrable deformation of the type IIB AdS5×S5 superstring action is presented and the original psu(2,2|4) symmetry is expected to become q deformed.
Foundations of the AdS5 × S5 superstring: I
We review the recent advances towards finding the spectrum of the AdS5 ? S5 superstring. We thoroughly explain the theoretical techniques which should be useful for the ultimate solution of the
S-matrix for strings on η-deformed AdS5 × S5
A bstractWe determine the bosonic part of the superstring sigma model Lagrangian on η-deformed AdS5 × S5, and use it to compute the perturbative world-sheet scattering matrix of bosonic particles of

On jordanian deformations of AdS5 and supergravity
We consider various homogeneous Yang-Baxter deformations of the AdS_5 x S^5 superstring that can be obtained from the eta-deformed superstring and related models by singular boosts. The jordanian
