This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The first measurement of the differential cross section of the associated production of a photon and a bottom quark in proton-proton collisions is presented. Protons are accelerated and brought into collision at a center-of-mass energy of 8 TeV by the Large Hadron Collider. The collisions are recorded with the ATLAS detector and correspond to an integrated luminosity of up to 20.2 fb-1. The measurement is performed in two regions of the absolute value of the photon pseudorapidity: from 0 to 1.37 and from 1.56 to 2.37. The measurement is performed as a function of the photon transverse energy, from 25 to 400 GeV in the former pseudorapidity region and from 25 to 350 GeV in the latter region. The relative uncertainty in the measurement varies between 13% and 54% and is dominated by the uncertainty in the efficiency of identifying jets containing bottom quarks. The ratio of the cross section in the two pseudorapidity regions is also measured to reduce the positively correlated systematic uncertainties in the measurement between the two regions. The measurement is compared to predictions of perturbative quantum chromodynamics at the leading order and at the next-to-leading order. At low transverse energy, a good agreement is observed between the measured and the predicted values. At high transverse energy, however, the measured values are observed to be up to a factor of two larger than the most precise predicted values. This measurement can help improve the modelling of bottom quarks in perturbative quantum chromodynamics." --

This book was released on 1998-02-28 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main focus of this book is on experimental results from electron-positron and electron-proton colliders and related theoretical questions, particularly on hadron production at energies from 1 to 100 GeV and higher. The topics discussed include photo- and electroproduction of heavy flavours, the photon structure function, total cross section, jet production and resonance production. The future of the field is also discussed, notably experiments at linear photon-photon colliders.

Available in PDF, EPUB and Kindle. Book excerpt: This volume reports on all aspects of high energy photon interactions using both photon and proton targets. Significant new results from the LEP and HERA experiments as well as from CLEO II and BELLE are presented. These data are confronted with diverse theoretical models. In particular, predictions of QCD in both the perturbative and the non-perturbative sector are extensively discussed. The prospects for gamma-gamma physics at future high energy colliders are also reviewed. In total 72 papers are collected.The proceedings have been selected for coverage in: ?

This book was released on 2012-12-02 with total page 1004 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first precision measurements on CP violation in the B system are reported. Both the BELLE and the BABAR collaboration presented, among others, results for sin 2ß with much improved accuracy. Results from the Sudbury Neutrino Observatory, SNO, also deserve to be mentioned. The convincing evidence of solar neutrino oscillations had been presented by SNO prior to the conference; a full presentation was given at the conference. An incredibly precise measurement of the anomalous magnetic moment of the muon is reported, a fresh result from the Brookhaven National Laboratory. Apart from these distinct physics highlights, there are also the first results from the new Tevatron run and from the relativistic heavy ion collider RHIC. Theorists write of our ever better understanding of the Standard Model and of what might lie beyond. Risky as it is to highlight only a couple of exciting subjects, it is merely meantto whet the appetite for further reading.
Download or read book Measurement of the Production Cross Section of the Photon Charm Final State in 8 TeV Proton proton Collisions Using the ATLAS Detector at the LHC written by Robert Keyes and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "This thesis presents the measurement of the production cross section of high energy isolated prompt photons in association with charm flavour jets in 20.1/fb of proton-proton collisions at a center of mass energy of 8 TeV using the ATLAS detector. Isolated prompt photons are well described theoretically and well measured experimentally, providing unique advantages when probing parton level dynamics and the content of the proton. As such, measurements of this type can be used in global parton distribution fits to better constrain the charm quark content of the proton in the Large Hadron Collider (LHC) environment. The differential cross sections are measured with respect to the photon transverse energy, ET[gamma], in two photon pseudorapidity regions: |[eta][gamma]|

This book was released on 2002 with total page 882 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proceedings of DIS 2001 present the most updated status of deep inelastic scattering (DIS) physics. Topics like structure function measurements and phenomenology, QCD studies in DIS and photoproduction, spin physics and diffractive interactions are reviewed in detail, with emphasis on those studies that push the test of QCD and the Standard Model to the limits of their present range of validity, towards both the very high and the very low four-momentum transfers in the lepton-proton scattering. Moreover, this workshop coincided with the transition between the first period of experimentation at the HERA ep collider at DESY and the start of the updated HERA II operation -- allowing a review of what has been learned up to now and a discussion on the main future directions of research in this field.
