Abstract / Description:We consider gluon and gluino scattering amplitudes in large N β-deformed View the MathML source 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 View the MathML source 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 View the MathML source SYM that breaks all the supersymmetry.
