Multijet production and double parton scattering at Tevatron

PDF Version Also Available for Download.

Description

We report the differential cross-section for events with large total transverse energies, based on 112 pb{sup -1} p{anti p} collisions at {radical}s = 1.8 TeV. The ratio of number of 3-jet to 2-jet events as a function of total transverse energy is also presented. Obtained results are compared with the QCD expectations. The properties of high mass six-jet events have been studied. Observed distributions are compared with the predictions of HER- WIG parton shower QCD, NJETS matrix element QCD, and a phase-space model in which events are uniformly distributed in the kinematic allowed region of phase space. A strong signal ... continued below

Description

We report the differential cross-section for events with large total transverse energies, based on 112 pb{sup -1} p{anti p} collisions at {radical}s = 1.8 TeV. The ratio of number of 3-jet to 2-jet events as a function of total transverse energy is also presented. Obtained results are compared with the QCD expectations. The properties of high mass six-jet events have been studied. Observed distributions are compared with the predictions of HER- WIG parton shower QCD, NJETS matrix element QCD, and a phase-space model in which events are uniformly distributed in the kinematic allowed region of phase space. A strong signal for Double Parton Scattering (DP) is observed in the process {anti p}p {yields} {gamma} + 3 jets + X, using data from the CDF experiment. The fundamental DP parameter {sigma}{sub eff} obtained, {sigma}{sub eff} = 14.5 + 1.7{sup 1.7}{sub -2.3} mb, represents a significant improvement over previous measurements.
