N2 - We consider gluon and gluino scattering amplitudes in large N β-deformed N = 4 SYM with real β. A direct inspection of the planar diagrams shows that the scattering amplitudes to all orders in perturbation theory are the same as in the undeformed N = 4 SYM theory. Using the dual σ-model description, we find the same equality at strong coupling to all orders in the σ-model loop expansion. Finally, we show that the same analysis holds for gluon scattering amplitudes in a three-parameter deformation of planar N = 4 SYM that breaks all the supersymmetry.
