Measurement of Properties of Electroweak Bosons with the DØ Detector
نویسنده
چکیده
This article reports three analyses of W and Z boson properties from the DØ experiment at the Fermilab Tevatron. The W boson mass measurement using 1 f b −1 DØ data is presented. This measurement reaches a 43 MeV precision on the W boson mass, which is currently the most precise result from a single experiment. It is used to place indirect constraint on the mass of the hypothetical Higgs boson. The W charge asymmetry analysis using 4.9 f b −1 DØ W → µν data to constrain the PDF uncertainty is reported. The measurement of effective electroweak mixing angle and the couplings of Z/γ * to light quarks from the analysis of Z/γ * forward-backward asymmetry based on 5 f b −1 DØ data is presented.

STUDY OF WZ PRODUCTION WITH THE DØ DETECTOR by KETINO KAADZE
In this Dissertation I present a detailed study of pp̄ → WZ production using fully leptonic decays of W and Z bosons with electrons and muons in the final state. Data used for the study were collected by the DØ detector at the Fermilab pp̄ collider with a centerof-mass energy of √ s = 1.96 TeV and correspond to 4.1 fb−1 of integrated luminosity. The most precise measurement of the WZ production c...
متن کاملElectroweak and Qcd Results from Dø for the Dø Collaboration
We present some of the results in the areas of QCD and Electroweak physics for Run II of the DØ experiment at the Fermilab Tevatron. QCD results include dijet angular decorrelations and inclusive jet and dijet cross sections. Electroweak results include the decay of Z bosons to tau pairs and several results on gauge boson pairs. No deviations from the Standard Model have been observed.

This paper presents the latest measurements of the properties of the top quark as determined by the DØ and CDF collaborations at the Fermilab Tevatron pp Collider. Both experiments have studied the all-hadronic decay mode of tt events. The top quark mass measurement has been refined over the past year, with the addition of new channels and a re-evaluation of some of the earlier ones. There are ...

Run 2 of the Tevatron collider at Fermilab has begun in the spring of 2001. During its first year of operation the Tevatron has delivered an integrated luminosity of approximately 30 pb −1 to the DØ experiment. These data have been used to commission the detector. The progress in understanding the detector performance and the prospects for an exciting physics program to be carried out in the ne...
