Electroweak Prospects for Tevatron RunII
The prospects of precision electroweak measurements from CDF and D0, using
RunII data, is reviewed.Comment: 4 pages; to appear in the Proceedings for the ICHEP-02 Conference,

Measurement of the W Mass from LEP2
In 1997 each LEP experiment collected approximately of data at
a center-of-mass energy of 183 GeV. These data yield a sample of candidate
events from which the mass of the W boson, M_W, is
measured. The preliminary LEP combined result, including data taken at \roots
= 161 and 172 GeV and assuming the Standard Model relation between the W decay
width and mass, is GeV, where the uncertainties correspond to experimental,
colour-reconnection/Bose-Einstein, and LEP beam energy respectively.Comment: 7 pages, 1 figure. Proceedings for talk 1-12 given at the DPF99

Recent LEP 2 Results from OPAL
In 1996, after another set of upgrades, LEP began running for the first time
at center-of-mass energies above the W-pair production threshold. This new
energy regime is rich in physics and offers new tests of the Standard Model,
increased sensitivity for search physics, and precision W physics. We summarize
the recent results from OPAL using 9.9 pb^-1 of data collected at \sqrt s =
161.3 GeV from June to August 1996.Comment: 26 pages, 15 figures, Latex, appb.sty included; Proceedings from the

Measurement of from LEP2
In 1997 each LEP experiment collected approximately 55 inv. pb of data at a center-of-mass energy of 183 GeV. These data yield a sample of candidate e+e- -> WW events from which the mass of the W boson, Mw, is measured. The LEP combined result, including data taken at roots = 161 and 172 GeV and assuming the Standard Model relation between the W decay width and mass, is Mw = 80.35 +/- 0.07 (exp) +/- 0.04 (CR) +/- 0.03 (E_beam) GeV, where the errors correspond to experimental, colour-reconnection/Bose-Einstein, and LEP beam energy uncertainties respectively
Top-Quark Physics Results from the Tevatron
The Tevatron's record luminosities enable a program systematically addressing
the physics of the top quark. The CDF and D0 experiments are pioneering
measurements across the full breadth of topics. Some of their most recent
results are summarized.Comment: 5 pages, proceedings for the CIPANP 2009 conferenc

World average top-quark mass
This paper summarizes a talk given at the Top2008 Workshop at La Biodola, Isola d Elba, Italy. The status of the world average top-quark mass is discussed. Some comments about the challanges facing the experiments in order to further improve the precision are offered
Top Quark Physics at the Tevatron
We review the field of top-quark physics with an emphasis on experimental
techniques. The role of the top quark in the Standard Model of particle physics
is summarized and the basic phenomenology of top-quark production and decay is
introduced. We discuss how contributions from physics beyond the Standard Model
could affect top-quark properties or event samples. The many measurements made
at the Fermilab Tevatron, which test the Standard Model predictions or probe
for direct evidence of new physics using the top-quark event samples, are
reviewed here.Comment: 50 pages, 17 figures, 2 tables; version accepted by Review of Modern
