Abstract
In the light gluino variant of the minimal supersymmetric model, gluin o pairs can be readily produced in collider experiments even if the sq uarks are arbitrarily heavy. This enhances the jet transverse energy d istributions. In addition, the slower running of the strong coupling c onstant in the presence of light gluinos leads to a further enhancemen t at higher transverse energies relative to the standard QCD expectati ons. Finally, the enhanced squark gluino production would lead to a Ja cobian peak in the E(T) distribution at about M((Q) over tilde)/2. The se effects are of about the right magnitude to explain anomalies obser ved by the CDF and DO Collaborations.
