  • An overview of recent electroweak physics results from the Tevatron is given. Properties of the W{sup {+-}} and Z{sup 0} gauge bosons using final states containing electrons and muons based on large integrated luminosities are presented. In particular, measurements of the W{sup {+-}} and Z{sup 0} production cross sections, the W-charge asymmetry and the measurement of the W-mass are summarized. Gauge boson self interactions are measured by studying gauge boson pair production and Emits on anomalous gauge boson couplings are discussed.
  • This writeup is an introduction to some of the experimental issues involved in performing electroweak and b physics measurements at the Fermilab Tevatron. In the electroweak sector, we discuss W and Z boson cross section measurements as well as the measurement of the mass of the W boson. For b physics, we discuss measurements of B{sup 0}/{bar B}{sup 0} mixing and CP violation. This paper is geared towards nonexperts who are interested in understanding some of the issues and motivations for these measurements and how the measurements are carried out.
  • The Run II physics program of CDF and D0 has just begun with the first 72 pb{sup -1} of analysis quality data collected at the center-of-mass energy of 1.96 TeV. The Electroweak measurements are among the first and most important benchmarks for the best understanding of the detectors and testing the Standard Model. We present measurements of the W and Z inclusive cross sections and decays asymmetries, recent results in di-boson physics and searches for new physics which make use of distinct electroweak signatures.
  • Recent measurements of processes involving the electroweak bosons, Z and W, performed at the Fermilab Tevatron Collider are summarized. The large integrated luminosities collected by both the D0 and CDF Collaborations enable precise measurements of differential single boson production cross sections, the determination of the W mass with unprecedented precision, and the observation of diboson production including ZZ.
  • The most recent Electroweak results from the Tevatron are presented. The importance of precise Standard Model measurements in the Higgs sector, quantum chromodynamics and searches for new physics is emphasized. Analyzed data correspond to 1-7 fb{sup -1} of integrated luminosity recorded by the CDF and D0 detectors at the Tevatron Collider at {radical}s = 1.96 TeV during the period between 2002-2010. The main goal of the Electroweak (EW) physics is to probe the mechanism of the EW symmetry breaking. An important aspect of these studies is related to precise measurements of the Standard Model (SM) parameters and tests of themore » SU(2) x U(1) gauge symmetry. Deviations from the SM may be indicative of new physics. Thus, the interplay between the tests of the 'standard' physics and searches for a 'nonstandard' physics is an important aspect of the EW measurements. The observables commonly used in these measurements are cross sections, gauge boson couplings, differential distributions, asymmetries, etc. Besides, many EW processes represent a non-negligible background in a Higgs boson and top quark production, and production of supersymmetric particles. Therefore, the complete and detailed understanding of EW processes is a mandatory precondition for early discoveries of very small new physics signals. Furthermore, several EW analyses represent a proving ground for analysis techniques and statistical treatments used in the Tevatron Higgs searches.« less
