6 We present a measurement of the top pair production cross section in pp collisions at √ s=1.96 TeV. We collect a data sample with an integrated luminosity of 194±11 pb −1 with the CDF II detector at the Fermilab Tevatron. We use an artificial neural network technique to discriminate between top pair production and background processes in a sample of 519 lepton+jets events, which have one isolated energetic charged lepton, large missing transverse energy and at least three energetic jets. We
