Abstract :
We consider the effects of a light gluino on the dijet angular distributions in pp collisions at s=1800 GeV. We show that the slower running of αs and the production qq,gg → gg do not significantly alter the normalized differential cross-sections. On the other hand, single u,d squard production qg → qg with subsequent q → qg results in dijets whose angular distributions are dramatically different from that in SM. The CDF data on dijet angular distributions with integrated luminosity of 106 pb−1 exclude u and d squarks in the mass ranges 190 ≤ m ≤ 650 and 200 ≤ m ≤ 630 GeV, respectively. We extend our analysis to lower energies and show that in a future experimental analysis for dijet mass below 240 GeV squarks will be observed or ruled out.
