This book was released on 2008 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Ph.D. thesis presents the measurement of inclusive jet cross sections in Z/?*→ e+e- events using 1.7 fb-1 of data collected by the upgraded CDF detector during the Run II of the Tevatron. The Midpoint cone algorithm is used to search for jets in the events after identifying the presence of a Z/?* boson through the reconstruction of its decay products. The measurements are compared to next-to-LO (NLO) pQCD predictions for events with one and two jets in the final state. The perturbative predictions are corrected for the contributions of non-perturbative processes, like the underlying event and the fragmentation of the partons into jets of hadrons. These processes are not described by perturbation theory and must be estimated from phenomenological models. In this thesis, a number of measurements are performed to test different models of underlying event and hadronization implemented in LO plus parton shower Monte Carlo generator programs. Chapter 2 is devoted to the description of the theory of strong interactions and jet phenomenology at hadron colliders. Chapter 3 contains the description of the Tevatron collider and the CDF detector. The analysis is described in detail in Chapter 4. Chapter 5 shows the measurement of those observables sensitive to non-perturbative effects compared to the predictions from several Monte Carlo programs. Chapter 6 discusses the final results and the comparison with theoretical expectations. Finally, Chapter 7 is devoted to the conclusions.

Download or read book Measurement of the Z/?* ({u2192} E+e-) + {u2265} N Jet Production Cross Sections in P$\bar{p}$ Collisions at {u221A}s written by and published by . This book was released on 2005 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of events with Z/?* bosons and hadronic jets produced at the Tevatron in p$ar{p}$ collisions at a center of mass energy of 1.96 TeV is presented. The data consist of approximately 14,000 Z/?* → e+e- decay candidates from 343 pb-1 of integrated luminosity collected with the D0 detector. Cross sections and jet production properties have been measured for Z/?* + ≥ 0 to 5 jet events. This measurement represents a significant improvement over previous measurements at the Tevatron, and it is the first at this center of mass energy with the D0 detector. The results are in good agreement with QCD predictions.

This book was released on 2010 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: The inclusive production of b-jets with a Z boson is an important background to searches for the Higgs boson in associated ZH → llb$ar{b}$ production at the Fermilab Tevatron collider. This thesis describes the most precise measurement to date of the ratio of inclusive cross sections ?(p$ar{p}$ → Z + b-jet)/?(p$ar{p}$ → Z + jet) when a Z boson decays into two electrons or muons. The measurement uses a data sample from p$ar{p}$ collisions at the center of mass energy √s = 1.96 TeV corresponding to an integrated luminosity of 4.2 fb-1 collected by the D0 detector. The measured ratio ?(Z + b-jet)/?(Z + jet) is 0.0187 ± 0.0021(stat) ± 0.0015(syst) for jets with transverse momentum pT > 20 GeV and pseudorapidity.

Book excerpt: Measurements of differential cross sections are presented for the production of a Z boson and at least one hadronic jet in proton-proton collisions at √s = 7 TeV, recorded by the CMS detector, using a data sample corresponding to an integrated luminosity of 4.9 inverse femtobarns. The jet multiplicity distribution is measured for up to six jets. The differential cross sections are measured as a function of jet transverse momentum and pseudorapidity for the four highest transverse momentum jets. The distribution of the scalar sum of jet transverse momenta is also measured as a function of the jet multiplicity. The measurements are compared with theoretical predictions at leading and next-to-leading order in perturbative QCD.
