Kinematic properties of four jet events taken during the 1988/89 run of the Tevatron at Fermilab are compared with the predictions of a leading order QCD calculation. Preliminary work on a search for double parton scattering is presented.

Kinematic properties of four-jet events in p[bar p] collisions at [radical]s = 1.8 TeV are compared with the predictions of leading order quantum chromodynamics. We place an upper limit on the double parton scattering cross of [sigma][sub DP] 120 nb (95% C.L.) for partons with transverse momenta greater than 18 GeV/c. Defining the effective cross section [sigma][sub eff] through the equation of [sigma][sub eff] = [sigma][sub DP] = [sigma][sub dijet]/([sup 2]/[sigma][sub eff]), where [sigma][sub dijet] is the cross section for two-jets events, the limit [sigma][sub eff] 3.9 mb (95% C.L.) is also placed. Implications for physics at the SSC ([radical]s = 40 TeV) are discussed.

We have searched for double parton scattering in the 4-jet channel with an integrated luminosity of 4.4 pb−1, collected using the D{O} detector during 1994-1995 Fermilab Collider run at a center of mass energy ((square root)s) of 1.8 TeV. We present the preliminary observation of a statistically significant excess of signal.
