We establish in perturbation theory the existence of fixed points along the renormalization group flow for QCD with an adjoint Weyl fermion and scalar matter reminiscent of magnetic duals of QCD [1-3]. We classify the fixed points by analyzing their basin of attraction. We discover that among these there are stable supersymmetric ones emerging from a generic nonsupersymmetric renormalization group flow once the mass operators have been properly subtracted away. We therefore conclude that four dimensional supersymmetry can emerge as a fixed point theory from a nonsupersymmetric Lagrangian. Our results suggest that supersymmetry can be viewed as an emergent phenomenon in four dimensional field theory complementing recent discoveries in lower number of dimensions [4, 5].
