Abstract
We confirm recent results obtained in a previous work by studying the Ising spin glass at finite magnetic field in four dimensions. Different approaches to this problem suggest the existence of a critical line similax to that found in mean-field theory but in a universality class different of the transition at zero magnetic field. Problems due to the strong nature of the finite-size corrections within a magnetic field are also discussed.
