This book was released on 2005 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present measurements of the inclusive Drell-Yan e+ e- differential cross section (d?/dMe+ e- and forward-backward asymmetry (AFB) as a function of the dielectron invariant mass over the range 70-400 GeV/c2. The data sample consists of 177.3 pb-1 of p$ar{p}$ collisions at √s = 1.96 TeV collected by the D0 detector. The results are consistent with the predictions of the standard model.

Available in PDF, EPUB and Kindle. Book excerpt: We present recent results on top quark pair production cross section and forward-backward asymmetry at the Tevatron. Three new cross section measurements from CDF and one new measurement from DO are presented that utilize the full dataset available. A new DO top cross section combination gives a ttbar production cross section of sigma ttbar = 7.83 + 0.46-0.45 (stat) + 0.64-0.53 (syst) +-0.48 (lumi). The new CDF cross section combination for ttbar production is found to be 7.0 +- 0.3 (stat) +- 0.4 (syst) +- 0.4 (lumi) pb giving a total uncertainty of 9%, very close to the that of the current best theoretical predictions. It is important to measure the top cross section in as many different channels as possible and investigate their compatibility. This is useful as new physics might show up differently in the different channels. Thus any significant discrepancy could be a sign of new physics. Three new measurements of the forward-backward asymmetry are also presented. The two CDF measurements unfold the observed asymmetry back to parton level in order to directly compare the values obtained with theoretical predictions. The DO measurement is not unfolded and therefore does not depend on the specific method used for unfolding.

This book was released on 2010 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation describes a measurement of the forward-backward asymmetry(A{sub FB}) in p{bar p} → Z/[gamma]* → ee events using 5.0 fb−1 data collected by the D0 detector at the Fermilab Tevatron. The AFB is measured as a function of the invariant mass of the electron-positron pair. Along with obtaining normalized differential cross section 1/[sigma] x d[sigma]/dM and Z to light quark couplings, we measured the Standard Model(SM) fundamental parameter, the effective weak mixing angle sin2 [theta]{sub eff}{sup lept}, with an unprecedented precise in light quark sector, namely the single D0 measurement has surpassed the LEP combination of four experiment results of inclusive hadronic charge asymmetry.

Book excerpt: Particle physics is a science about the symmetries of our world. The Standard Model is the fundamental theory of microworld. Particle dynamics in the Standard Model obeys strict symmetry laws with explicit experimental consequences. Priority problems of particle physics based on the Standard Model are more accurate theoretical predictions, experimental measurements and data analysis, proof of existence or non-existence of supersymmetry, top quark properties, Higgs boson, exotic quark states, and physics of neutrinos. In this collection of articles, many of these problems are discussed. We recommend this book for students, graduate students, and scientists working in the field of high energy physics.
