A New Form of Soft Supersymmetry Breaking


Abstract in English

Using the components of real and chiral superfields subject to an internal U(N)xU(N) gauge symmetry, an action is constructed in which the gauginos are in a different representation of the group than the gauge bosons. This action with broken supersymmetry satisfies criteria that ensure that it is free of quadratic divergences to all orders. A two-loop calculation provides insight as to how cancellations of quadratic divergences manifest themselves at that level of perturbation theory.
