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.
Book Synopsis Electroweak Physics at the LHC by : Matthias U. Mozer
Download or read book Electroweak Physics at the LHC written by Matthias U. Mozer and published by Springer. This book was released on 2016-03-24 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book discusses the recent experimental results obtained at the LHC that involve electroweak bosons. The results are placed into an appropriate theoretical and historical context. The work pays special attention to the rising subject of hadronically decaying bosons with high boosts, documenting the state-of-the-art identification techniques and highlighting typical results. The text is not limited to electroweak physics in the strict sense, but also discusses the use of electroweak vector-bosons as tool in the study of other subjects in particle physics, such as determinations of the proton structure or the search for new exotic particles. The book is particularly well suited for graduate students, starting their thesis work on topics that involve electroweak bosons, as the book provides a comprehensive description of phenomena observable at current accelerators as well as a summary of the most relevant experimental techniques.
Book Synopsis W Boson Charge Asymmetry in the Muonic Decay Channel at the CMS Experiment by : Grayson Laurent Williams
Download or read book W Boson Charge Asymmetry in the Muonic Decay Channel at the CMS Experiment written by Grayson Laurent Williams and published by . This book was released on 2011 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Large Hadron Collider is a new circular particle accelerator designed to collide bunches of protons at a beam energy of sqrt(s) = 7 TeV. One of the two large general-purpose detectors is the Compact Muon Solenoid. This paper will provide a measurement of the W boson cross section and charge asymmetry in the decay channel W to muon + neutrino over the entire 2010 (35.9 inverse picobarn) dataset, as a means of testing detector performance and of constraining Parton Distribution Functions, as well as testing theoretical predictions in the new energy regime. The cross section and charge asymmetry were measured by first imposing a series of cuts, then using sideband subtraction to remove background process contributions. Systematic and statistical uncertainties were also calculated. The cross section was found to be consistent with theoretical predictions, and the overall charge asymmetry was also found to be consistent with theoretical predictions.
Book Synopsis Associated Production of W + Charm in 13 TeV Proton-Proton Collisions Measured with CMS and Determination of the Strange Quark Content of the Proton by : Svenja Karen Pflitsch
Download or read book Associated Production of W + Charm in 13 TeV Proton-Proton Collisions Measured with CMS and Determination of the Strange Quark Content of the Proton written by Svenja Karen Pflitsch and published by Springer Nature. This book was released on 2020-08-18 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The associated production of a W boson and a single charm quark (W+c) is the only process in proton-proton collisions that directly probes the strange quark content of the proton. In this thesis, W+charm production is measured in proton-proton collisions at the LHC at 13 TeV, as recorded by the Compact Muon Solenoid (CMS) experiment. The analysis focuses on the identification of W bosons in their leptonic decay to a muon and a neutrino and charm quarks are tagged via the full reconstruction of D*-Mesons. The measured cross sections of W+c production are used, in combination with other relevant CMS results and the most precise HERA DIS data, in a QCD analysis to determine the strange quark content of the proton. The resulting strange quark distribution and suppression, with respect to the other light sea quarks, are in good agreement with those obtained in neutrino scattering experiments and extend their kinematic reach.
Book Synopsis New Era For Cp Asymmetries: Axions And Rare Decays Of Hadrons And Leptons by : Ikaros I Bigi
Download or read book New Era For Cp Asymmetries: Axions And Rare Decays Of Hadrons And Leptons written by Ikaros I Bigi and published by World Scientific. This book was released on 2021-07-14 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is dedicated to Lev Okun, who passed away in November 2015. He was a true pioneer in probing fundamental dynamics.The book has two objectives. First is to showcase Okun's impact for decades since 1963, when he published his remarkable book Weak Interaction of Elementary Particles. Second is to present the current progress of our scientific community in the studies of our Universe. New directions and possible future developments are discussed, often using the past as a guide. The authors mostly focus on CP asymmetries in the transitions of hadrons and leptons, but they also discuss their rare decays, and talk about axions and supersymmetry, and possible connections with dark matter, extra dimensions, baryogenesis and multiverse.This book is suitable for readers who know quantum mechanics and quantum field theories in general.

Available in PDF, EPUB and Kindle. Book excerpt: We present a measurement of the muon charge asymmetry from W boson decays using 0.3 fb−1 of data collected at (square root)s = 1.96 GeV between 2002 and 2004 with the D0 detector at the Fermilab Tevatron p{bar p} Collider. We compare our findings with expectations from next-to-leading-order calculations performed using the CTEQ6.1M and MRST04 NLO parton distribution functions. Our findings can be used to constrain future parton distribution function fits.

Download or read book Measurement of the W Boson Mass with the ATLAS Detector written by Oleh Kivernyk and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes a measurement of the W boson mass with the ATLAS detector based on the data-set recorded by ATLAS in 2011 at a centre-of-mass energy of 7 TeV, and corresponding to 4.6 inverse femtobarn of integrated luminosity. Measurements are performed through template fits to the transverse momentum distributions of charged leptons and to transverse mass distributions of the W boson, in electron and muon decay modes in various kinematic categories. The individual measurements are found to be consistent and their combination leads to a value of m_W = 80371.1 ± 18.6 MeV. The measured value of the W boson mass is compatible with the current world average of m_W = 80385 ± 15 MeV. The uncertainty is competitive with the current most precise measurements performed by the CDF and D0 collaborations.
Book Synopsis Measurement of the Charge Ratio of Atmospheric Muons with the CMS Detector by :
Download or read book Measurement of the Charge Ratio of Atmospheric Muons with the CMS Detector written by and published by . This book was released on 2010 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present a measurement of the ratio of positive to negative muon fluxes from cosmic ray interactions in the atmosphere, using data collected by the CMS detector both at ground level and in the underground experimental cavern at the CERN LHC. Muons were detected in the momentum range from 5 GeV/c to 1 TeV/c. The surface flux ratio is measured to be 1.2766 \pm 0.0032(stat.) \pm 0.0032 (syst.), independent of the muon momentum, below 100 GeV/c. This is the most precise measurement to date. At higher momenta the data are consistent with an increase of the charge ratio, in agreement with cosmic ray shower models and compatible with previous measurements by deep-underground experiments.
