Available in PDF, EPUB and Kindle. Book excerpt: This letter reports a measurement of the muon charge asymmetry from W Boson produced in proton-proton collisions at a centre-of-mass energy of 7 TeV with the ATLAS experiment at the LHC. The asymmetry is measured in the W → [mu][nu] decay mode as a function of the muon pseudorapidity using a data sample corresponding to a total integrated luminosity of 31 pb-1. The results are compared to predictions based on next-to-leading order calculations with various parton distribution functions. The measurement provides information on the u and d quark momentum fractions in the proton.

Available in PDF, EPUB and Kindle. Book excerpt: We present a measurement of the W boson production charge asymmetry using the W → e[nu] decay channel. We use data collected the Collider Detector at Fermilab (CDF) from p{bar p} collisions at √s = 1.96 TeV. The data were collected up to February 2006 (Run II) and represent an integrated luminosity of 1 fb−1. The experimental measurement of W production charge asymmetry is compared to higher order QCD predictions generated using MRST2006 and CTEQ6 parton distribution functions (PDF). The asymmetry provides new input on the momentum fraction dependence of the u and d quark parton distribution functions (PDF) within the proton over the fraction of proton's momentum range from 0.002

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present a measurement of the W boson production charge asymmetry in p$ar{p}$→W+X→e?+X events at a center of mass energy of 1.96 TeV, using 9.7 fb-1 of integrated luminosity collected with the D0 detector at the Fermilab Tevatron Collider. The neutrino longitudinal momentum is determined by using a neutrino weighting method, and the asymmetry is measured as a function of the W boson rapidity. The measurement extends over wider electron pseudorapidity region than previous results and is the most precise to date, allowing for precise determination of proton parton distribution functions in global fits.

Download or read book The Charge Asymmetry in W Bosons Produced in P Anti-p Collisions at Center of Mass Energy - 1.96 TeV. written by Julie M. Torborg and published by . This book was released on 2005 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary mode of production of W{sup +} bosons in a p{bar p} collider is u + {bar d} {yields} W{sup +}. The u quark generally carries more momentum than the {bar d} and the resultant W{sup +} tends to be boosted in the proton direction. Similarly, W bosons are boosted in the anti-proton direction. This is observed as an asymmetry in the rapidity distributions of positive and negative W bosons. Measurement of this asymmetry serves as a probe of the momentum distribution of partons within the proton. These distributions are required as input to the calculation of every p{bar p} production cross section. This thesis presents the first measurement at D0 of the charge asymmetry of the W boson production cross section as measured in W {yields} ev decays in 0.3 fb{sup -1} of p{bar p} collisions collected with the D0 Detector. Theoretical predictions made using the CTEQ6.1M and MRST(2004) parton distribution functions are compared with the measurement.

This book was released on 2014 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes a precise measurement of the muon charge asymmetry in inclusive pp [RIGHTWARDS ARROW] W + X production at the center of mass energy of s = 7 TeV of colliding protons. The data sample was collected with the Compact Muon Solenoid detector at the Large Hadron Collider and corresponds to an integrated luminosity of 4.7 fb[-]1 . The measurement was performed in 11 bins of the muon pseudorapidity within [eta] 2.4 range and for two thresholds on its transverse momentum: pT 25 GeV and pT> 35 GeV. Precise measurement of the muon charge asymmetry provides an important test for the Standard Model physics. Thanks to the large data sample, containing more than 20 million W [RIGHTWARDS ARROW] [MICRO SIGN][nu] events, statistical precision is greatly improved compared with the previous lepton charge asymmetry results at the LHC. Total absolute uncertainty on the charge asymmetry varies within 0.2% [-] 0.4% in different muon pseudorapidity bins. The result provides significant constraints on the parton distribution functions of the proton in the Bjorken-x range from 0.001 to 0.1.

Available in PDF, EPUB and Kindle. Book excerpt: Our first study of W boson production in pPb collisions is presented, for bosons decaying to a muon or electron, and a neutrino. The measurements are based on a data sample corresponding to an integrated luminosity of 34.6 nb-1 at a nucleon–nucleon centre-of-mass energy of √sNN= 5.02 TeV, collected by the CMS experiment. The W boson differential cross sections, lepton charge asymmetry, and forward–backward asymmetries are measured for leptons of transverse momentum exceeding 25 GeV/c , and as a function of the lepton pseudorapidity in the.
