Description
After the first observation of the inclusive single top-quark production in the s- and t-channels by both CDF and D0, the 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 (CDF) and 2.3/fb (D0) of data, respectively. For a top quark mass of 170 GeV/c^2, a cross section of 2.76 +0.58 -0.47 pb is extracted while the CKM matrix element |V_tb| is measured to be 0.88 ± 0.07 with a 95% C.L. lower limit of |V_tb| > 0.77.
