Tevatron combination of single top quark production and Vtb measurement

Conference ·
OSTI ID:1001999
After the first observation of the inclusive single top-quark production in the s- and t-channels by CDF and D0, both Tevatron collaborations combined their measurements using the distributions of their multivariate discriminants. A Bayesian analysis is used to extract the cross section at a center of mass energy of 1.96 TeV from 3.2 fb{sup -1} (CDF) and 2.3 fb{sup -1} (D0) of data, respectively. For a top quark mass of 170 GeV/c{sup 2}, a cross section of 2.76 + 0.58 - 0.47 pb is extracted while the CKM matrix element |V{sub tb}| is measured to be 0.88 {+-} 0.07 with a 95% C.L. lower limit of |V{sub tb}| > 0.77.
