The measurements are performed in events with two leptons (electrons or muons) in the final state. Results of the cross section measurement in events with and without b-quark identification are obtained and combined. The measured value is = 168 ± 18 (stat . ) ± 14 (syst . ) ± 7 (lumi . ) pb, consistent with predictions from the standard model. The top quark mass m top is reconstructed with two different methods, a full kinematic analysis and a matrix weighting technique.
