Observation of single top quark production and measurement of |Vtb|with CDF

Abstract: We report the observation of electroweak single top quark production in 3.2 fb −1 of pp collision data collected by the Collider Detector at Fermilab at √ s = 1.96 TeV. Candidate events in the W +jets topology with a leptonically decaying W boson are classified as signal-like by four parallel analyses based on likelihood functions, matrix elements, neural networks, and boosted decision trees. These results are combined using a super discriminant analysis based on genetically evolved neural networks in order to… Show more

“…On the other hand the signal acceptance for the tight muon categories is geometrically limited, therefore a set of lower quality muon identification criteria, loose muons, was developed. Loose muons were used in other analysis [86] to increase the signal yield. These are the main requirements of the loose muons algorithms:…”
