Combination of CDF and D0 results on the W boson mass and width
Physical Review D - Particles, Fields, Gravitation and Cosmology 70:9 (2004)
Abstract:
The results based on 1992-95 data (Run 1) from the CDF and D0 experiments on the measurements of the W boson mass and width are presented, along with the combined results. We report a Tevatron collider average MW = 80.456 ± 0.059 GeV. We also report the Tevatron collider average of the directly measured W boson width TW = 2.115 ± 0.105 GeV. We describe a new joint analysis of the direct W mass and width measurements. Assuming the validity of the standard model, we combine the directly measured W boson width with the width extracted from the ratio of W and Z boson leptonic partial cross sections. This combined result for the Tevatron is TW = 2.135 ± 0.050 GeV. Finally, we use the measurements of the direct total W width and the leptonic branching ratio to extract the leptonic partial width Γ(W → eν) = 224 ± 13 MeV.Measurement of the average time-integrated mixing probability of b-flavored hadrons produced at the Fermilab Tevatron

Abstract:
We have measured the number of like-sign (LS) and opposite-sign (OS) lepton pairs arising from double semileptonic decays of b and [Formula Presented] hadrons, pair produced at the Fermilab Tevatron collider. The data samples were collected with the Collider Detector at Fermilab during the 1992–1995 collider run by triggering on the existence of [Formula Presented] or [Formula Presented] candidates in an event. The observed ratio of LS to OS dileptons leads to a measurement of the average time-integrated mixing probability of all produced b-flavored hadrons which decay weakly, [Formula Presented] that is significantly larger than the world average [Formula Presented] © 2004 The American Physical Society.Direct photon cross section with conversions at CDF -: art. no. 074008
