Measurements of single top quark production cross sections and |Vtb| in pp?collisions at s=1.96 TeV
Original language description
We present measurements of production cross sections of single top quarks in /ppbar collisions at s=1.96//TeV in a data sample corresponding to an integrated luminosity of 5.4//fb1 collected by the D0 detector at the Fermilab Tevatron Collider. We selectevents 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 ?(/ppbar/rargaptb+X,tqb+X)=3.430.730.74//pb and use itto extract the CKM matrix element 0.79<|Vtb|1 at the 95% C.L. We also measure ?(/ppbar/rargaptb+X)=0.680.380.35//pb and ?(/ppbar/rargaptqb+X)=2.860.690.63//pb when assuming, respectively, tqb and tb production rates as predicted by the standard model.
