Rev. Lett. 112 051601; Hollowood et al 2014 J. Phys. A: Math. Theor. 47 495402). One class of these, the k deformations associated to the more general q deformations but with a root of unity, has been shown to be related to a particular discrete deformation of the principal chiral models and (semi-)symmetric space sigma models involving a gauged WZW model. We conjecture a form for the exact S-matrices of the bosonic integrable field theories of this type. The S-matrices imply that the theories have a hidden infinite dimensional affine quantum group symmetry. We provide some evidence, via quantum inverse scattering techniques, that the theories do indeed possess the finite-dimensional part of this quantum group symmetry.engAdS/CFTintegrable deformationsintegrable field theoryquantum groupsstring theoryS-matrices and quantum group symmetry of k-deformed sigma modelsArtigo10.1088/1751-8113/49/46/465201Acesso aberto2-s2.0-849940207192-s2.0-84994020719.pdf
