Abstract
We compare predictions of three supersymmetry scenarios [(A) ${m}_{g\ifmmode \tilde{}\else \~{}\fi{}}$>${m}_{q\ifmmode \tilde{}\else \~{}\fi{}}$ \ensuremath{\simeq}50 GeV, (B) ${m}_{q\ifmmode \tilde{}\else \~{}\fi{}}$>${m}_{g\ifmmode \tilde{}\else \~{}\fi{}}$ \ensuremath{\simeq}50 GeV, and (C) ${m}_{q\ifmmode \tilde{}\else \~{}\fi{}}$ \ensuremath{\simeq}100 GeV, ${m}_{g\ifmmode \tilde{}\else \~{}\fi{}}$ \ensuremath{\simeq}3 GeV] proposed to explain large-missing-${p}_{T}$ events at the CERN pp\ifmmode\bar\else\textasciimacron\fi{} collider in terms of scalar-quark or gluino decays to a light photino. We evaluate fusion cross sections for monojets and multijets and present distributions in missing ${p}_{T}$, jet ${E}_{T}$, jet pseudorapidity, jet invariant mass, and cluster transverse mass. Scenarios A and B give about equal one-jet and two-jet event rates, soft missing-${p}_{T}$ and jet-${E}_{T}$ distributions and occasional prompt leptons; scenario B gives large jet invariant masses, even for monojets. Scenario C yields monojet dominance and Jacobian peaks in missing ${p}_{T}$ and jet ${E}_{T}$; the present UA1 data favor this latter description.
