    A measurement of the tt̄ production cross section in pp̄ using dilepton events was discussed. The tt̄ production cross section in the dilepton channel were observed to be 7.0 2.4 -2.1(stat) +1.6 -1.1(syst) ±0.4(lum) pb. The data and the SM prediction in event yield and key kinematic distributions were found to be in good agreement. It was observed that the measured tt̄ cross section agrees well with the full next-to-leading order SM prediction of 6.7 +0.7 -0.9 pb.
