The light gluino mass window revisited

The precise measurements of the \electroweak observables" performed at LEP and SLC are well consistent with the standard model predictions. Deviations from the standard model arising from vacuum polarization diagrams (also called \weak loop corrections") have been constrained in a model-independent manner with the " formalism. Within the same formalism, additional deviations from new physics production processes can also be constrained, still in a model-independent way. For instance, a 95% C.L. limit of
