Book excerpt: The CDF and D0 Collaborations have measured the inclusive jet cross section using 1992--93 collider data at (square root)s = 1,800 GeV. The D0 measurement is higher than NLO QCD predictions, though within systematic uncertainties. The CDF measurement is in very good agreement with NLO QCD predictions for transverse energies (E{sub T}) below 200 GeV. However it is systemically higher than NLO QCD predictions for E{sub T} above 200 GeV. The CDF measurement of two-jet mass and total transverse energy spectra also show a similar excess above QCD predictions at higher E{sub T}.

Available in PDF, EPUB and Kindle. Book excerpt: Quantum Chromodynamics (QCD) is the gauge theory that governs the strong interactions between quarks and gluons inside hadrons like, for example, protons and neutrons. At the Tevatron at Fermilab, protons and antiprotons collide at very high energy. In those collisions, collimated jets of hadrons are produced along the direction of struck quarks and gluons in the final state. The measurement of the inclusive jet production cross section for central jets constitutes one of the cornerstones of the jet physics program since it provides a stringent test of pQCD predictions over almost nine orders of magnitude. This Doctoral Thesis presents a measurement of the inclusive jet production cross section using the data collected by the CDF experiment in Run II. The longitudinally invariant Kt algorithm, infrared safe to all orders in pQCD, has been used in order to search for jets in the final state. This measurement is compared to pQCD NLO calculations where non-perturbative effects from the underlying event and the fragmentation of partons into jets of hadrons have been taken into account.

Available in PDF, EPUB and Kindle. Book excerpt: A preliminary measurement is presented of the inclusive jet production cross section in p{bar p} collisions at a center-of-mass energy of (square root)s = 1960GeV: The data was taken with the D0 detector and represents an integrated luminosity of (almost equal to) 900 pb−1 of Tevatron RunII data. The cross section is studied as a function of jet transverse momentum (p{sub T}) and rapidity (y) and compared to perturbative QCD predictions in next-to-leading order including two-loop threshold corrections.

Book excerpt: Measurements of the inclusive jet cross section and the dijet angular distribution using data from the Tevatron are presented Comparisons to NLO QCD show good agreement below 250 GeV, but CDF data show an excess at higher E{sub T}; qualitative agreement is seen between the CDF and D0 cross sections. Analysis of the dijet angular distributions exclude quark compositeness below 2.1 TeV.

Book excerpt: We report a new measurement of the pseudorapidity and transverse-energy (E{sub T}) dependence of the inclusive jet production cross section in p{bar p} collisions at √s = 1:8 TeV using 95 pb−1 of data collected with the D0 detector at the Fermilab Tevatron. The differential cross section d2?/(dE{sub T}d?) is presented up to {vert_bar}?{vert_bar} = 3, significantly extending previous measurements. The results are in good overall agreement with next-to-leading order predictions from QCD, indicate a preference for certain parton distribution functions, and provide the world's best constraint on the gluon distribution at high parton momentum fraction x.

Book excerpt: Jets have been used to verify the theory of quantum chromodynamics (QCD), measure the structure of the proton and to search for the physics beyond the Standard Model. In this article, we review the current status of jet physics at the Tevatron, a (square root)s = 1.96 TeV p{bar p} collider at the Fermi National Accelerator Laboratory. We report on recent measurements of the inclusive jet production cross section and the results of searches for physics beyond the Standard Model using jets. Dijet production measurements are also reported.

Download or read book Review of Recent Tevatron Jet, W written by and published by . This book was released on 2009 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document reviews several recent measurements at the Fermilab Tevatron, including the cross sections of inclusive jet, dijet production, the cross sections of electroweak boson (W or Z) production in association with inclusive or heavy-flavor (b or c) jets, and b-jet shapes. In addition, searches for new physics using the dijet angular distributions are discussed. These analyses are based on integrated luminosities of 0.3--2.5/fb of p-{bar p} collisions at (square root)s = 1.96 TeV, collected with the CDF and D0 detectors. The results directly test the leading order and next-to leading order calculations of perturbative quantum chromodynamics and provide constraints on the parton distribution functions, gluon-splitting contribution, and physics beyond the standard model.

Download or read book Jet Physics at the LHC written by Klaus Rabbertz and published by Springer. This book was released on 2016-10-11 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the latest experimental results on jet physics from proton-proton collisons at the LHC. Jets allow to determine the strong coupling constant over a wide range of energies up the highest ones possible so far, and to constrain the gluon parton distribution of the proton, both of which are important uncertainties on theory predictions in general and for the Higgs boson in particular.A novel approach in this book is to categorize the examined quantities according to the types of absolute, ratio, or shape measurements and to explain in detail the advantages and differences. Including numerous illustrations and tables the physics message and impact of each observable is clearly elaborated.
