Book excerpt: The CDF and D0 experiments have both collected large samples of W and Z bosons with the last Tevatron collider run (1995--1996) using p{anti p} collisions at (square root)s = 1.8 TeV. The author presents the results of QCD studies with vector bosons that cover a large range of transverse momentum space, pT, making this a testing ground for both perturbative and non-perturbative QCD. The measurement of the W and Z cross section, their width, the W and Z transverse momentum distribution and the angular distribution of electrons in W decays are described in this paper.

Book excerpt: The CDF and D0 collaborations have used recent data taken at the Tevatron to perform QCD tests with W and Z bosons decaying leptonically. D0 measures the production cross section times branching ratio for W and Z bosons. This also gives an indirect measurement of the total width of the W boson: [Lambda][sub W] = 2.126 [+-] 0.092 GeV. CDF reports on a direct measurement of [Lambda][sub W] = 2.19 [+-] 0.19 GeV, in good agreement with the indirect determination and Standard Model predictions. D0's measurement of the differential d[sigma]/dp[sub T] distribution for W and Z bosons decaying to electrons agrees with the combined QCD perturbative and resummation calculations. In addition, the d[sigma]/dp[sub T] distribution for the Z boson discriminates between different vector boson production models. Studies of W + Jet production at CDF find the NLO QCD prediction for the production rate of W + [ge] 1 Jet events to be in good agreement with the data.

Download or read book Electro-Weak, QCD and Top Physics at the Tevatron written by and published by . This book was released on 1993 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1992--1993 Tevatron collider run ended yesterday. ≈21 (16)pb−1 of p{bar p} collisions at √S = 1800 GeV were collected at CDF (D0). New measurements of the W and Z cross section x branching ratios indicate that [Gamma](W) is 2.033 ± 0.069 ± 0.057 GeV. The upper limit for the top quark mass, if it is produced in W decays, is 62 GeV/c3. Gauge boson pair production studies are beginning to constrain electro-weak parameters. No neutral gauge bosons with mass > M{sub z} have appeared. Inclusive jet production and angular distribution studies are compared to NLO perturbative QCD predictions. A new topological jet analysis from CDF is sensitive to the low x gluon distribution. The direct photon cross section shows a steeper fall-off with E{sub t} than does the theory prediction. D0 has one candidate t{bar t} event in the dilepton mode. The lower limit on M{sub T{sub op}} has been raised to 99 GeV/c2.

Book excerpt: Results in QCD physics at the Tevatron from the D0 and CDF collaborations are presented, including results in jet production, photon production, W/Z bosons plus jets, and heavy-flavor jets. The importance of these topics in tuning Monte-Carlo simulations, constraining the parton distribution functions, and measuring cross sections of QCD processes which contribute significant backgrounds to searches for new and important physics is discussed.
Book Synopsis Measurement of the Associated Production of Z Bosons and Jets in P-pbar Collisions at the Tevatron by :
Download or read book Measurement of the Associated Production of Z Bosons and Jets in P-pbar Collisions at the Tevatron written by and published by . This book was released on 2009 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: Higher order QCD corrections to W and Z boson production do not only manifest themselves in the generation of high transverse momenta of the weak bosons, but these QCD effects become directly visible in the production of jets in association with the weak bosons. Studying these processes is not only interesting from the perspective of testing perturbative QCD, but also to constrain a major background to many Standard Model (SM) of non-SM physics signals, e.g. top pair and single top production, searchers for the Higgs boson, leptoquarks and supersymmetric particles. This thesis describes a measurement of Z/[gamma]* + jets production in p$\bar{p}$ collisions at √s = 1.96 TeV in the decay channel Z/[gamma]* → [mu]+[mu]-. An integrated luminosity of L≈ 1fb-1 collected by the D0 detector at the Tevatron between August 2002 and February 2006 has been used. Differential production cross sections as function of the transverse energy of the first, second and third leading jet are measured. The distributions are corrected for acceptance and migration effects back to hadron level using an iterative unfolding method. Comparison of the measured cross sections to event generators, which include part of the higher order corrections are presented.

Book Synopsis Multiple Parton Interactions at the LHC by : Paolo Bartalini
Download or read book Multiple Parton Interactions at the LHC written by Paolo Bartalini and published by World Scientific Publishing. This book was released on 2018-11-08 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many high-energy collider experiments (including the current Large Hadron Collider at CERN) involve the collision of hadrons. Hadrons are composite particles consisting of partons (quarks and gluons), and this means that in any hadron–hadron collision there will typically be multiple collisions of the constituents — i.e. multiple parton interactions (MPI). Understanding the nature of the MPI is important in terms of searching for new physics in the products of the scatters, and also in its own right to gain a greater understanding of hadron structure. This book aims at providing a pedagogical introduction and a comprehensive review of different research lines linked by an involvement of MPI phenomena. It is written by pioneers as well as young leading scientists, and reviews both experimental findings and theoretical developments, discussing also the remaining open issues.

Download or read book Test of QCD in Multijet Final States at the Tevatron written by and published by . This book was released on 2011 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this contribution, some of the recent QCD results on jet production from the CDF and D0 experiments in Run II of the Tevatron are discussed. In particular, results include cross section measurements for dijet and trijet production, study of jet substructure and measurements of W/Z+jets cross sections. The measurements are compared with the theoretical predictions. The QCD program at the Tevatron proton-antiproton collider revolves around the jet physics. Jets are collimated sprays of hadrons generated by the fragmentation of partons originating from the hard scattering. The measurements of jets production cross section at the Tevatron provide stringent test of perturbative QCD predictions, information on the strong coupling constant, [alpha]s, and constraints on proton parton distribution functions, PDFs. The deviations from the pQCD predictions could translate into a hint of new physics. In addition, these processes form sizable backgrounds to both, the Standard Model (SM) and beyond SM physics processes. Therefore, good understanding of jets production is essential to perform precise physics measurements or searches for new physics phenomena. In this contribution, a review of some recent QCD results from the CDF [1] and D0 [2] experiments is presented. Various analyses use proton-antiproton collision data from the Fermilab Tevatron at the center of mass energy √s = 1.96 TeV corresponding to integrated luminosities of 0.7 fb−1 to 8 fb−1. The results are corrected for the experimental effects and presented at the 'particle level'. The theory predictions are corrected for the hadronization and underlying effects which are obtained from the parton shower Monte Carlo (MC) simulations.

Book excerpt: The Tevatron hadron collider provides the unique opportunity to study Quantum Chromodynamics, QCD, at the highest energies. The results summarized in this talk, although representing different experimental objects, as hadronic jets and electromagnetic clusters, serve to determine the fundamental input ingredients of QCD as well as to search for new physics. The authors present results from QCD studies at the Tevatron from Run 1 data, including jet and direct photon production, and a measurement of the strong coupling constant.
