Description
We show that in a class of gauge mediation models with tree level R-symmetry breaking, where supersymmetry and R-symmetries are broken by different fields, the gaugino mass either vanishes or finds contribution from loop level R-symmetry breaking. Thus tree-level R-symmetry breaking is either no-go or redundant for phenomenology model building. Attempts to overcome the no-go are discussed.
