On non-supersymmetric fixed points in five dimensions

Abstract

Abstract We generalize recent results regarding the phase space of the mass deformed E 1 fixed point to a full class of five-dimensional superconformal field theories, known as X 1,N . As in the E 1 case, a phase transition occurs as a supersymmetry preserving and a supersymmetry breaking mass deformations are appropriately tuned. The order of such phase transition could not be unequivocally determined in the E 1 case. For X 1,N , instead, we can show that at large N there exists a regime where the phase transition is second order. Our findings give supporting evidence for the existence of non-supersymmetric fixed points in five dimensions.
