The measurement of the shape of the boson rapidity distribution for p $$\bar{p}$$ → Z/γ* → e⁺e^- + X events at a center-of-mass energy of 1.96 TeV is presented in this thesis. Data, with an integrated luminosity of L = 9.86 fb^-1, collected with the D0 detector during the whole RunII data taking period of the Fermilab Tevatron p$$\bar{p}$$ collider has been used. The measurement is made for events with electron-positron mass 66 < M_ee < 111 GeV. The current result gives the best precision of the boson rapidity shape at the Tevatron. It signi cantly reduces the uncertainty in the boson rapidity range |y| > 2:3. Predictions of Next-to- Leading-Order (NLO) QCD theory with CTEQ and MSTW parton distribution functions are found to agree well with the data over the full rapidity range.
