3 v 1 1 8 Se p 19 96 Top Quark Physics Results from CDF and D 0
I summarize recent top quark physics results from the Fermilab Tevatron experiments. Since the observation of the top quark by CDF and D0 in 1995, the experimental focus has shifted to a detailed study of the top quark’s properties. This article describes recent measurements of the top quark production cross section, mass, kinematic properties, branching ratios, Vtb, and the W polarization in t...
متن کاملCombination of Single Top Quark Production Results from CDF
Recently, the CDF experiment at the Fermilab Tevatron has used complementary methods to make multiple measurements of the singly produced top quark cross section. All analyses use the same dataset with more than 2 fb of CDF data and event selection based on W + 2 or W + 3 jet events with at least one b-tagged jet. However, due to differences in analysis techniques these results are not fully co...
متن کاملMeasurement of Single Top Quark Production in 7.5 fb−1 of CDF Data Using Neural Networks
We report a measurement of single top quark production in lepton plus jets final state using 7.5 fb−1 of pp̄ collision data collected by CDF Run II experiment. We select events in the W + jets topology consistent with the signature of a charged lepton (electron or muon), large missing transverse energy ( 6 ET ) from the W boson decay and two or three jets, at least one of them is required to be ...
متن کاملObservation of single top at CDF
We present observation of electroweak single top quark production using 3.2 fb−1 of data collected by the CDF experiment. Candidate events are selected for further classification by five parallel analysis techniques: one using a likelihood discriminant, one using a matrix-element discriminant, one using decision trees, one using a neural network, and one using a complementary dataset. The resul...

We report a combination of the CDF and D0 measurements of the inclusive single top quark production cross section in the sand t-channels, σs+t, in pp̄ collisions at a center of mass energy of 1.96 TeV. The total integrated luminosity included in CDF’s analysis is 3.2 fb−1 and D0’s analysis has 2.3 fb−1. A Bayesian analysis is used to extract the cross section from the distributions of multivaria...
متن کاملSingle Top Quark Production at the Fermilab Tevatron Collider
First evidence for single top quark production has recently been found by both the D0 and CDF experiments. By combining three analyses, D0 measured a cross section of σ (pp̄ → tb+X, tqb+X) = 4.7± 1.3 pb, with a significance of 3.6 standard deviations, and CDF’s matrix elements analysis measured a cross section of σ (pp̄ → tb+X, tqb+X) = 3.0 −1.1 pb, with a significance of 3.1 standard deviations....
