Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: We consider sample of inclusive [gamma] + 3 jet events collected by the D0 experiment. The double parton fraction (f{sub DP}) and effective cross section [sigma]{sub eff}, a process-independent scale parameter related to the parton density inside the nucleon, are measured in three intervals of the second (ordered in p{sub T}) jet transverse momentum p{sub T}{sup jet2} within the 15 ≤ p{sub T}{sup jet2} ≤ 30 GeV range. Also we measured cross sections as a function of the angle in the plane transverse to the beam direction between the transverse momentum (p{sub T}) of the [gamma] + leading jet system and p{sub T} of the other jet for [gamma] + 2 jet, or p{sub T} sum of the two other jets for [gamma] + 3 jet events. The results are compared to different models of multiple parton interactions (MPI) in the PYTHIA and SHERPA Monte Carlo (MC) generators.

Available in PDF, EPUB and Kindle. Book excerpt: We have used a sample of photon+3 jets events collected by the D0 experiment with an integrated luminosity of about 1 fb−1 to determine the fraction of events with double parton scattering (f{sub DP}) in a single ppbar collision at √s = 1.96 TeV. The DP fraction and effective cross section (sigma{sub eff}), a process-independent scale parameter related to the parton density inside the nucleon, are measured in three intervals of the second (ordered in p{sub T}) jet transverse momentum pT{sub jet2} within the range 15

Book Synopsis Multiple Parton Interaction Studies at DØ by :
Download or read book Multiple Parton Interaction Studies at DØ written by and published by . This book was released on 2016 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here, we present the results of studies of multiparton interactions done by the DØ collaboration using the Fermilab Tevatron at a center of mass energy of 1.96 TeV. We also present three analyses, involving three distinct final signatures: (a) a photon with at least 3 jets ([gamma] + 3jets), (b) a photon with a bottom or charm quark tagged jet and at least 2 other jets ([gamma] + b/c + 2jets), and (c) two J/ [psi] mesons. The fraction of photon + jet events initiated by double parton scattering is about 20%, while the fraction for events in which two J/ [psi] mesons were produced is 30 ± 10. While the two measurements are statistically compatible, the difference might indicate differences in the quark and gluon distribution within a nucleon. Finally, this speculation originates from the fact that photon + jet events are created by collisions with quarks in the initial states, while J/ [psi] events are produced preferentially by a gluonic initial state.
