Single Top Production and Top Properties at the Tevatron for the Cdf and Dd Collaborations
نویسنده
چکیده
We summarize recent measurements made at the Tevatron Collider using top event candidates. Cross section and mass measurements are discussed in a separate contribution to these Proceedings. Here we report on studies of the top P T distribution in tt production and studies of single top production. Properties of top decays examined are: BF(t ! Wb)/BF(t ! Wq), helicity amplitudes of W's from top decays and correlations of tt decay products. Searches for new physics in rare top decays and a search for a state X ! tt are also reported.

TeVatron Results on Top Quark Physics
The CDF and D0 collaborations at Fermilab’s Tevatron pp̄ collider have in place an extensive program to measure fundamental properties of the top quark. Recent results from Run I ( √ s = 1.8 TeV) and Run II ( √ s = 1.96 TeV) on the top quark’s production, mass, and decays are presented here. All results are consistent within their uncertainties with the Standard Model expectations for the top qu...
متن کاملMeasurements of Top Quark Properties at the Tevatron
The top quark was discovered in 1995 1,2 by the CDF and D0 / collaborations. Its large mass suggest it is strongly associated with the mechanism of electro-weak symmetry breaking, and makes it the fermion with the largest coupling to the standard model (SM)-expected, but not yet found, Higgs boson. These reasons make the top quark potentially sensitive to new physics, which can be revealed thro...
متن کاملTop Quark Pair Production and Properties Measurements at the Tevatron
The Tevatron proton-antiproton collider at Fermilab with its centre of mass energy of 1.96 TeV is currently the only source for the production of top quarks. This report reflects the current status of measurements of the top quark pair production cross section and properties performed by the CDF and DØ Collaborations. Utilising datasets of up to two fb, these measurements allow unprecedented pr...
متن کاملSearch for Single-top Production at the Tevatron
This article reports on recent searches for single-top-quark production by the CDF and DØ collaborations at the Tevatron. Neither two CDF analyses, using data corresponding to 695 pb of integrated luminosity, nor a DØ search based on 370 pb of data can establish a signal for this standard model process. These null results translate in upper limits on the cross section of 2.9 pb for the t-channe...
