We consider the decay of3 S 1 quarkonia into a photon and two Goldstone fermions in a model realizing supersymmetry in a nonlinear way. We derive a lower bound of 3.5 GeV for the scale of spontaneous supersymmetry breaking from Υ-decays. We show that the decay of a3 S 1 quarkonium into two Goldstone fermions is forbidden in the order we consider. |
