a Search for Double Parton Interactions in 1.8 Tev Proton-Antiproton Collisions.
Abstract
4-jet events produced in PP collisions at 1.8 TeV and observed in the CDF detector at the Fermilab collider are examined for evidence of double parton interactions. Double parton 4-jet events are separated from other types of 4 -jet events using topological variables. An upper limit on the double parton cross section is set, expressed as a lower limit on the effective proton cross section; sigma_{eff} > 5.14 mb (95% confidence level). This limit is consistent with theoretical predictions.
