This dissertation reports on measurements of inclusive cross sections times branching fractions into electrons for W and Z bosons produced in p[anti p] collisions at[radical]s= 1.8 TeV. From an integrated luminosity of 84.5 pb[sup[minus]1] recorded in 1994--1995 by the D0 detector at the Fermilab Tevatron[Lambda] the cross sections are measured to be[sigma]p[anti p][r-arrow] W+ X[center-dot] B(W[r-arrow] e[nu])= 2,310[+-] 10 (stat)[+-] 50 (Syst)[+-] 100 (lum) pb and[sigma](p[anti p][r-arrow] Z+ X)[center-dot] B(Z[r-arrow] ee)= 221[+-] 3 (stat)[+-] 4 (Syst)[+-] 10 (lum) pb. The cross section ratio R is determined to be[sigma](p[anti p][r-arrow] W+ X)[center-dot] B(W[r-arrow] e[nu])/[sigma](p[bar p][r-arrow] Z+ X)[center-dot] B(Z[r-arrow] ee)= 10.43[+-] 0.15 (stat)[+-] 0.20 (syst)[+-] 0.10 (NLO)[Lambda] and R is used to determine B(W[r-arrow] e[nu])= 0.1044[+-] 0.0015 (stat)[+-] 0.0020 (syst)[+-] 0.0017 (theory)[+-] 0.0010 (NLO)[Lambda] and[Lambda][sub W]= 2.169[+-] 0.031 (stat)[+-] 0.042 (syst)[+-] 0.041 (theory)[+-] 0.022 (NLO) GeV. The latter is used to set a 95% confidence level upper limit on the partial decay width of the W boson into non-standard model final states[Lambda][Lambda][sub W][sup inv][Lambda] of 0.213 GeV.
