Measurement of the fraction of t(t)over-bar production via gluon-gluon fusion in p(p)over-bar collisions at root s=1.96 Tev
(American Physical Society, 2009-02)
We present a measurement of the ratio of the tt̅ production cross section via gluon-gluon fusion to the total tt̅ production cross section in pp̅ collisions at √s=1.96 TeV at the Tevatron. Using a data sample with an ...
Direct Measurement of the W Production Charge Asymmetry in p(p)over-bar Collisions at root s = 1.96 TeV
(American Physical Society, 2009-03)
We present the first direct measurement of the W production charge asymmetry as a function of the W boson rapidity yW in p(p)over-bar collisions at √s=1.96 TeV. We use a sample of W→eν events in data from 1 fb[superscript ...
Search for Exclusive Z-Boson Production and Observation of High-Mass pp-bar-->p gamma gamma p-bar-->pl+l-p-bar Events in pp-bar Collisions at s=1.96 TeV
(American Physical Society, 2009-06)
This Letter presents a search for exclusive Z boson production in proton-antiproton collisions at √s=1.96 TeV, using the CDF II detector. No exclusive Z→l+l- candidates are observed and the first upper limit on the exclusive ...
First Measurement of the t(t) over bar Differential Cross Section d sigma/dM(t(t) over bar) in p(p) over bar Collisions at root s=1.96 TeV
(American Physical Society, 2009-06)
We present a measurement of the t(t) over bar differential cross section with respect to the t(t) over bar invariant mass, d sigma/dM(t(t) over bar), in p(p) over bar collisions at √s=1.96 TeV using an integrated ...
Searching the inclusive l gamma EslashT+b-quark signature for radiative top quark decay and non-standard-model processes
(American Physical Society, 2009-07)
We compare the inclusive production of events containing a lepton (ℓ), a photon (γ), significant transverse momentum imbalance (E̸[subscript T]), and a jet identified as containing a b-quark, to SM predictions. The search ...
First measurement of the ratio of branching fractions [script B](Lambdab0-->Lambdac+µ-[overline nu ]µ)/[script B](Lambdab0-->Lambdac+pi-)
(American Physical Society, 2009-02)
This article presents the first measurement of the ratio of branching fractions B(Λb0→Λc+μ-ν̅ μ)/B(Λb0→Λc+π-). Measurements in two control samples using the same technique B(B̅ 0→D+μ-ν̅ μ)/B(B̅ 0→D+π-) and B(B̅ 0→D*(2010)+μ-ν̅ ...
Search for Top-Quark Production via Flavor-Changing Neutral Currents in W+1 Jet Events at CDF
(American Physical Society, 2009-04)
We report on a search for the non-standard-model process u(c)+g→t using pp̅ collision data collected by the Collider Detector at Fermilab II detector corresponding to 2.2 fb[superscript -1]. The candidate events are ...
Measurement of the top quark mass at CDF using the "neutrino phi weighting" template method on a lepton plus isolated track sample
(American Physical Society, 2009-04)
We present a measurement of the top quark mass with tt̅ dilepton events produced in pp̅ collisions at the Fermilab Tevatron (√s=1.96 TeV) and collected by the CDF II detector. A sample of 328 events with a charged ...
Observation of Electroweak Single Top-Quark Production
(American Physical Society, 2009-08)
We report the observation of single top-quark production using 3.2 fb[superscript -1] of pp̅ collision data with √s=1.96 TeV collected by the Collider Detector at Fermilab. The significance of the observed data is 5.0 ...
Search for a Fermiophobic Higgs Boson Decaying into Diphotons in pp-bar Collisions at sqrt[s]=1.96 TeV
(The American Physical Society, 2009-08)
A search for a narrow diphoton mass resonance is presented based on data from 3.0 fb[superscript -1] of integrated luminosity from pp̅ collisions at √s=1.96 TeV collected by the CDF experiment. No evidence of a resonance ...
