    • AMY Collaboration, Y. Sugimoto et al., Phys. Lett. B369, 86 (1996), in their search for single-photon events at KEK TRISTAN requires that the photon points to the interaction region. The resolution, which presumably improves with increasing photon energy, quoted in this analysis is 4.4 cm for 6 GeV photons, and is derived from the angular resolution of about 2.5°. Assuming that SUSY events can be triggered via jets or leptons, the fine calorimeter segmentation would allow for the determination of the photon impact parameter in the D0 experiment with a resolution of a few centimetes if (Formula presented) decays before, or within, the electromagnetic calorimeter; this resolution would be somewhat degraded for decays within the hadronic calorimeter. A measurement of photon energy would not be possible if (Formula presented) decayed in the muon chamber. We thank Mike Jones, Mike Peters, and Steve Olsen for discussions about this issue.

    • We have checked, for example, that for (Formula presented) TeV the width for (Formula presented) decays into a gravitino varies between (Formula presented) and (Formula presented) eV for the four cases (a)–(d) and for the entire range of (Formula presented) that we have considered in Fig. 22. This is to be compared to the decay width into other SUSY modes which is typically ∼1 MeV (∼1 keV) for two-body (three-body) decays of (Formula presented)

    • We have explicitly computed the sparticle production cross sections with RGE boundary conditions for the extreme case where there are four (Formula presented) messenger multiplets. Since (for the same choice of (Formula presented) sparticles are heavier than in the minimal case studied in the text, (Formula presented) values as small as 10 TeV are now consistent with the data. For (Formula presented) TeV which yields a production cross section (Formula presented) fb before any cuts, we find that the production of sleptons is comparable to or, at most, 2–3 times higher than (Formula presented) and (Formula presented) production. We have explicitly checked that for these scenarios, leptonic decays of charginos and neutralinos dominate, so that SUSY signals would indeed be dominated by events without any jet activity
