Book excerpt: We present measurements of jet production and isolated prompt photon production in p{bar p} collisions at √s = 1.8 TeV from the 1988--89 run of the Collider Detector at Fermilab (CDF). To test QCD with jets, the inclusive jet cross section (p{bar p} → J + X) and two jet angular distributions (p{bar P} → JJ + X) are compared to QCD predictions and are used to search for composite quarks. The ratio of the scaled jet cross sections at two Tevatron collision energies (√s= 546 and 1800 GeV) is compared to QCD predictions for X{sub T} scaling violations. Also, we present the first evidence for QCD interference effects (color coherence) in third jet production (p{bar p} → JJJ + X). To test QCD with photons, we present measurements of the transverse momentum spectrum of single isolated prompt photon production (p{bar p} → [gamma] + X), double isolated prompt photon production (p{bar p} → [gamma][gamma] + X), and the angular distribution of photon-jet events (p{bar p} → [gamma] J + X). We have also measured the isolated production ratio of [eta] and [pi]° mesons (p{bar p} → [eta] + X)/(p{bar p} → [pi]° + X) = 1.02 ± .15(stat) ± .23(sys).

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the Proceedings of the 17th Workshop of the INFN ELOISATRON Project on "QCD at 200 TeV", held at the "Ettore Majorana" Centre for Scientific Culture, EMCSC, Erice, Trapani, Italy, in the period 11-17 June 1991. The new multi-Te V frontiers of Subnuclear Physics are no more beyond our imagination. A conceptual design of the highest energy (100+100 TeV) proton-proton collider -the ELOISA TRON -already exists. Intensive R & D studies are on the go to develop the most promising and innovative detector technologies for the highest energy and luminosity. QCD (Quantum Chromo-Dynamics) will be the theory to describe the expected Physics scenario of future S upercolliders. The purpose of the Workshop was therefore to review the recent status of QCD in High Energy interactions and to discuss the novel aspects of Perturbative and Non Perturbative QCD with special emphasis on future experimental studies at Super-High Energy Colliders, up to the 200 Te V limit. The topics were: - Classical QCD: particle multiplication, multiplicities and spectra, jet profiles, coherence effects, etc. - Hadron interaction cross-sections and structure functions at Super-High Energies, small-x behaviour, QCD Pomeron, "hot spots"--QCD fragmentation models, present and future. - Artificial neural networks in High Energy Physics. - New theoretical aspects of QCD at Super-High Energies (instanton-induced large cross sections, baryon number violation and peculiar multi-quark production events, etc.)

Book Synopsis QCD Tests and New Physics Search with Jets at CDF. by :
Download or read book QCD Tests and New Physics Search with Jets at CDF. written by and published by . This book was released on 1993 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dijet invariant mass spectrum at a center of mass energy √s = 1.8 TeV measured at the Tevatron Collider by CDF in the 1988--1989 run is presented. Comparison with leading order and next-to-leading order QCD theoretical calculation is performed. A search for a possible quark compositeness and for axigluons, while not showing evidence for new physics, allows one to put limits on the compositeness mass scale [Kappa]{sub c} and on the axigulon mass M{sub a}. Preliminary results for the inclusive jet and the total transverse energy cross section from the high statistics data collected in the present run are shown.
Book Synopsis Quantum Chromodynamics by : Günther Dissertori
Download or read book Quantum Chromodynamics written by Günther Dissertori and published by Oxford University Press. This book was released on 2003-02-06 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an introduction to Quantum Chromodynamics (QCD), the theory of strong interactions. It covers in full detail both the theoretical foundations and the experimental tests of the theory. Although the experimental chapters focus on recent measurements, the subject is placed into historical perspective by also summarizing the steps which led to the formulation of QCD. Measurements are discussed as they were performed by the LEP experiments at CERN, or at hadron-hadron and lepton-hadron colliders such as the TEVATRON at Fermilab and HERA at DESY. Emphasis is placed on high energy tests of QCD, such as measurements of the strong coupling constant, investigations of the non-abelian structure of the underlying gauge group, determinations of nucleon structure functions, and studies of the non-perturbative hadronization process. This excellent text gives a detailed overview of how QCD developed in the 20th century and where we stand with respect to a quantitative understanding after the turn of the millenium. The text is intended for graduate and postgraduate students as well as researchers, and includes numerous problems and solutions.
Book Synopsis The Deconfinement Transition of QCD by : Claudia Ratti
Download or read book The Deconfinement Transition of QCD written by Claudia Ratti and published by Springer Nature. This book was released on 2021-06-14 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last few years, numerical simulations of QCD on the lattice have reached a new level of accuracy. A wide range of thermodynamic quantities is now available in the continuum limit and for physical quark masses. This allows a comparison with measurements from heavy ion collisions for the first time. Furthermore, calculations of dynamical quantities are also becoming available. The combined effort from first principles and experiment allows to gain an unprecedented understanding of the properties of quark-gluon plasma. This concise text, geared towards postgraduate students and newcomers to the field, carefully introduces and reviews the state-of-the-art techniques and results from lattice simulations and connects them to the experimental information from RHIC and the LHC.
Book Synopsis Measurement of Quarkonium Polarization to Probe QCD at the LHC by : Valentin Knünz
Download or read book Measurement of Quarkonium Polarization to Probe QCD at the LHC written by Valentin Knünz and published by Springer. This book was released on 2017-01-07 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis discusses in detail the measurement of the polarizations of all S-wave vector quarkonium states in LHC proton-proton collisions with the CMS detector. Heavy quarkonium states constitute an ideal laboratory to study non-perturbative effects of quantum chromodynamics and to understand how quarks bind into hadrons. The experimental results are interpreted through an original phenomenological approach, which leads to a coherent picture of quarkonium production cross sections and polarizations within a simple model, dominated by one single color-octet production mechanism. These findings provide new insights into the dynamics of heavy quarkonium production at the LHC, an important step towards a satisfactory understanding of hadron formation within the standard model of particle physics.

Book excerpt: CDF has recently concluded a very successful 1992--93 data run in which an integrated luminosity of 21.3 pb −1 was written to tape.

Download or read book Jet Physics at CDF. written by and published by . This book was released on 1997 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present high E{sub T} jet measurements from CDF at the Fermilab Tevatron Collider. The incfilusive jet cross section at √s = 1800 GeV with - 5 times more data is compared to the published CDF results, preliminary D0 results, and next-to-leading order QCD predictions. The ∑E{sub T} cross section is also compared to QCD predictions and the dijet angular distribution is used to place a limit on quark compositeness. The inclusive jet cross section at √s = 630 GeV is compared with that at 1800 GeV to test the QCD predictions for the scaling of jet cross sections with √s. Finally, we present momentum distributions of charged particles in jets and compare them to Modified Leading Log Approximation predictions.

The size of the data sample already compares to that of Run I. Results presented here include the measurement of the inclusive jet cross section, a search for new particles decaying to dijets, and a study of diffractive dijet events.
