Measurements of single top quark production cross sections and vertical bar V(tb)vertical bar in p(p)over-bar collisions at sqrt(s)=1.96 TeV
Original language description
We present measurements of production cross sections of single top quarks in p (p) over bar collisions at sqrt(s) = 1.96 TeV in a data sample corresponding to an integrated luminosity of 5.4 fb(-1) collected by the D0 detector at the Fermilab Tevatron Collider. We select events with an isolated electron or muon, an imbalance in transverse energy, and two, three, or four jets, with one or two of them containing a bottom hadron. We obtain an inclusive cross section of sigma(p (p) over bar -} tb + X, tqb +X) = 3.43(-0.74)(+0.73) pb and use it to extract the CKM matrix element 0.79 { vertical bar V(tb)vertical bar {= 1 at the 95% C.L. We also measure sigma(p{(p)over bar} -} tb + X) = 0.68(-0.35)(+0.38) pb and sigma(p (p) over bar -} tqb + X) = 2.86(-0.63)(+0.69) pb when assuming, respectively, tqb and tb production rates as predicted by the standard model.
