Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Physics, 2011. === In title on title page, "the square root of sigma" appears as the mathematical symbol, and "sigma" appears as the lower-case Greek letter. Cataloged from PDF version of thesis. === Includes bibliographical references (p. 165-172). === From March until November 2010 the Compact Muon Solenoid 36 pb-1 of pp collisions at [the square root of sigma]= 7 TeV. One of the first precision Model that can be performed with this data is the measurement cross section and the charge asymmetry in the cross section. measurements are performed in the electron decay channel. The experiment recorded tests of the Standard of the W-production In this thesis, both results obtained are: [sigma](W -> ev) = 10.48 ± 0.03(stat.) 0.15(syst.) ± 0.09(th.) ± 0.42(lumi.)nb [sigma](W+ -> e+v, U(W+ - ez) = 1.430 ± 0.008(stat.) ± 0.022(syst.) ± 0.029(th.) [sigma](W- ->e-v) The measurements agree with state-of-the-art NNLO QCD calculations with the latest parton distribution functions. === by Pieter Bruno Bart Everaerts. === Ph.D.
