Abstract

The measurement of the shape of the Z boson rapidity distribution for drell-yan events at a center-of-mass energy of 1.96 TeV is presented in this thesis. Data collected with the D0 detector during the whole RunII period of the Fermilab Tevatron proton-antiproton collider are used. By using these data with an integrated luminosity of up to L = 9.86~$fb^{-1}$, the uncertainties on the rapidity distribution in the forward region are significantly reduced compared with previous measurements. The measurement is made for events with electron-positron mass 66 < M(ee) < 111 GeV. Predictions of Next-to-Leading-Order(NLO) QCD theory with CTEQ and MSTW parton distribution functions (PDFs) are found to agree well with the data over the full rapidity range.
