Titre  Strongly gammadeformed N = 4 SYM as an integrable CFT 
Résumé  We demonstrate by explicit multiloop calculation that gammadeformed planar N = 4 SYM, supplemented with a set of doubletrace counterterms, has two nontrivial fixed points in the recently proposed double scaling limit, combining vanishing ’t Hooft coupling and large imaginary deformation parameter. We provide evidence that, at the fixed points, the theory is described by an integrable nonunitary fourdimensional CFT. We find a closed expression for the fourpoint correlation function of the simplest protected operators and use it to compute the exact conformal data of operators with arbitrary Lorentz spin. We conjecture that both conformal symmetry and integrability should survive in gammadeformed planar N = 4 SYM for arbitrary values of the deformation parameters.
