Abstract

Abstract We discuss systematically the consistency of light gluinos with data on perturbative QCD from deep inelastic scattering, quarkonia, jets at LEP, and the total hadronic cross-section in e + e − annihilation on the Z peak and elsewhere. We demonstrate that, in addition to the well-known increase in the value of α s ( m Z ) inferred from lower-energy data due to the slower running of α s in the presence of light gluinos, the value of α s ( m Z ) extracted from the LEP data must also be increased, as a result of including the effects of virtual light gluinos. The effect of these increases in other estimates of α s ( m Z ) is to make them more consistent with the value extracted from the total e + e − cross-section, which would otherwise appear distinctly higher. We discuss the possibility of looking for light gluinos in four-jet events at LEP, and their possible implications for scaling violations at HERA.
