Single jet and single photon production in proton-antiproton collisions ande+−e−-annihilation in a supersymmetric model
AbstractWe consider the production of Goldstone fermions accompanied by a single jet or a single photon in proton-antiproton collisions ande+e−-annihilation in a model realizing supersymmetry in a nonlinear way. Since the Goldstone fermions are neutrino-like particles, the experimental signature to look for is a single hard jet or photon together with missing energy. Interpreting the five single jet events and two single photon events reported recently from the CERNp
$$\bar p$$
 in this sense, we obtain a scale of spontaneous supersymmetry breaking of the order of 70 GeV. We show that this may imply a detectable rate of single photon production ine+e−-annihilation at present PETRA energies. We also calculate the ratio of single jet to single photon events in proton-antiproton collisions.
