Book Description
This thesis reports on the measurement of the W and Z boson inclusive production cross sections ([sigma][sub W] and[sigma][sub Z]) times electronic branching ratios (Br(W[r-arrow] e[nu]) and Br(Z[r-arrow] ee)) in p[anti p] collisions at[radical]s= 1.8 TeV. The analysis is based on 12.8 pb[sup[minus]1] of data taken in the 1992--1993 run by the D0 detector at the Fermilab Tevatron collider; the cross sections were measured to be:[sigma][sub W][center-dot] Br(W[r-arrow] e[nu])= 2.36[+-] 0.02[+-] 0.07[+-] 0.13 nb and[sigma][sub Z][center-dot] Br(Z[r-arrow] ee)= 0.218[+-] 0.008[+-] 0.008[+-] 0.012 nb. The first error is statistical, the second error represents the non-luminosity systematic error, and the third error shows the uncertainty in the luminosity determination. Future prospects for similar measurements based on larger samples of data are discussed.

Book Description
This thesis reports on the measurement of the W and Z boson inclusive production cross sections (?{sub W} and?{sub Z}) times electronic branching ratios (Br(W → e?) and Br(Z → ee)) in p{anti p} collisions at √s = 1.8 TeV. The analysis is based on 12.8 pb{sup −1} of data taken in the 1992--1993 run by the D0 detector at the Fermilab Tevatron collider; the cross sections were measured to be:?{sub W} · Br(W → e?) = 2.36 ± 0.02 ± 0.07 ± 0.13 nb and?{sub Z} · Br(Z → ee) = 0.218 ± 0.008 ± 0.008 ± 0.012 nb. The first error is statistical, the second error represents the non-luminosity systematic error, and the third error shows the uncertainty in the luminosity determination. Future prospects for similar measurements based on larger samples of data are discussed.

Book Description
Measurements of W and Z boson production cross sections in pp collisions at [square root] s = 5.02TeV and [square root] s = 13TeV are presented. Data was collected by the CMS experiment at the LHC during low-pileup data taking periods in 2017. The corresponding integrated luminosity for the data is 299.1 ± 5 pb−1 ( [square root] s = 5.02TeV) and 199.3 ± 4 pb−1 ( [square root] s = 13TeV), with an average number of pile-up interactions [[mu] = 3 ([mu] = 2). Cross sections and cross section ratios are reported, with final states in electron and muon channels.

Book Description
The cross sections for W and Z production in p[bar p] collisions at [radical]s = 1.8 TeV are measured using the D0 detector at the Fermilab Tevatron collider. The detected final states are W [yields] ev[sub e], Z [yields] e[sup +]e[sup [minus]], W [yields] [mu]v[sub [mu]], and Z [yields] [mu][sup +][mu][sup [minus]]. In the ratio of these measurements, many common sources of systematic error cancel and we measure R = [sigma], (p[bar p] [yields] W) [center-dot] Br(W [yields] lv)/ [sigma], (p[bar p] [yields] Z) [center-dot] Br(Z [yields] l[sup +]l[sup [minus]]). Assuming standard model couplings, this result is used to determine the width of the W bosom and to set a limit on the decay W[sup +] [yields] t[bar b].

Book Description
This dissertation presents measurements of the inclusive production cross sections for W and Z gauge bosons decaying through the electron channel with p{bar p} collisions at a center-of-mass energy of 1.96 TeV. The ratio of these cross sections is then used to extract the W total width. The Standard Model (SM) of electroweak and strong interactions is a collection of theories which together encompass what is currently known about the elementary particles that make up matter and the forces through which they interact. Experimentalists are constantly searching for violations of the Standard Model by making precision measurements of predicted interactions. The decay of the W boson is one such interaction. The rate of its decay is reflected in its width which is predicted to high precision using Standard Model-based calculations. Therefore, a high precision experimental width measurement would be very sensitive to any such violation. In principle the W and Z boson production cross sections could also be good Standard Model tests. However, a precise knowledge of integrated luminosity is required which is unfortunately difficult to obtain at the Tevatron. In fact, the W and Z cross section results can be used to obtain a more precise luminosity measurement. The data set consists of a total integrated luminosity of 177 pb{sup -1} collected from September 2002 to September 2003 using the D0 detector at Fermilab.

Book Description
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.
