Untwisting the symmetries of β-deformed Super-Yang-Mills

Abstract

We demonstrate that the planar real-β-deformed Super-Yang-Mills theory possesses an infinitely-dimensional Yangian symmetry algebra and thus is classically integrable. This is achieved by the introduction of the twisted coproduct which allows us to lift the apparent N = 1 supersymmetry first to the full N = 4 symmetry of the parent N = 4 SYM theory, and subsequently to its Yangian.
