H. Jeremie et al., IMPROVED METHOD FOR DETECTING THE EFFECT OF GLUINOS IN 4-JET EVENTS AT LEP, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 373(1), 1996, pp. 97-101
The usual method of searching for the effect of gluinos in four-jet ev
ents from hadronic decays of the Z(0) at LEP uses a comparison between
theoretical and experimental angular correlations of the four jets. T
he sensitivity of this method can be substantially improved by extendi
ng it to include a comparison of jet-masses, assuming the masses of th
e jets containing the new particles are larger than those of ordinary
quarks.
