Measurement of Jet Production with the ZEUS Detector
Deep Inelastic Scattering
Author: Masahiro Kuze
Publisher: World Scientific
ISBN: 9812706704
Category : Science
Languages : en
Pages : 996
Book Description
These proceedings present the most up-to-date status of deep inelastic scattering (DIS) physics. Topics such as structure function measurements and phenomenology, quantum chromodynamics (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 leptonproton scattering.

Studies of Jet Production with the DO Detector

Languages : en
Pages : 21
Book Description
During the first collider run at the Tevatron, the DO experiment has accumulated a large sample of events with jet final states, covering a jet E{sub T} range from about 30 to 400 GeV and pseudorapidities up to? = 3.2. First results about the transverse energy flow as a function of the jet cone size R are obtained and presented. The study of the two leading E{sub T} jets in events results in a measurement of the dijet angular distribution 1/?d?/d? as well as the triple differential cross section d3?/dE{sub T}d?1d?2 over a rapidity region not explored before. The correlation between E{sub T} of two jets and their distance in pseudorapidity is outlined as a test of resummation techniques and compared to a recent theoretical prediction. Finally distributions are presented characterizing the topology of 3 jet events and they are compared to parton shower Monte Carlos̀ and to an O(?{sub s}3) prediction at the tree level.

Measurement of the Production Cross Section of Jets in Association with a Z Boson in 8 TeV Proton-proton Collisions with the ATLAS Detector

Pages :
Book Description
"This thesis presents the measurement of the production cross sections of jets in association with a Z boson in proton-proton collisions at √s = 8 TeV with an integrated luminosity of 20.3 fb−1 recorded by the ATLAS experiment at the Large Hadron Collider at CERN. Inclusive and differential Z/[gamma]∗(→ e+e−)+jets cross sections are measured for jets with a transversemomentum pT(jet) > 30 GeV and rapidity |y(jet)| 4.4. Z boson candidates are identified by their decay into electron pairs. In order to stringently probe the modelling of Z/[gamma]∗+jets production by Monte Carlo generators in regions of high-pT phase space typical for Higgs boson decay and searches for new physics, events with high-pT final states are investigated. High-pT final states are defined as events with either pT(Z) 300 GeV or pT(leading jet) > 300 GeV. A set of four observables, sensitive to the topology of the event, are measured for the standard event selection as well as in the regions of high-pT phase space. The results from data are unfolded to particle level and compared to calculations of the matrix element from Monte Carlo generators Alpgen+Pythia and Sherpa interfaced to a parton shower. The results show that Sherpa tends to model Z/[gamma]∗+jets production in high-pT regions of phase space much better than Alpgen+Pythia." --

Book Description
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: ?
