The recently observed hadronic single- and multijet events accompanied by large missing p/sub T/ can be consistently explained by gluinos (g), produced via qq-bar,gg..-->..g g with an optimal mass of m/sub g/ = 35 to 45 GeV. This result agrees surprisingly well with theoretical predictions of the minimal N = 1 supergravity model. Adopting the theoretically somewhat less appealing alternative where scalar quarks (q) are lighter than gluinos such that they are dominantly produced via qq-bar,gg..-->..q q, the events can also be explained by scalar quarks in a similar mass range. Currently available data, including the observed jet properties, cannot meaningfully distinguish between these two mechanisms. In addition we present detailed predictions for cross sections and distributions in , p/sub T//sup miss/, p/sub T//sup jet/, and invariant observed jet masses for gluino as well as scalar-quark production at present and forthcoming CERN pp-bar collider energies (..sqrt..s = 540 and 620 GeV). Realistic tests are suggested which would allow discrimination between gluinos and scalar quarks in the near future.
