Resumen:	The tt̅ spin correlation at production is a fundamental prediction of QCD and a potentially incisive test of new physics coupled to top quarks. We measure the tt̅ spin state in pp̅ collisions at √s=1.96 TeV using 1001 candidate events in the lepton plus jets decay channel reconstructed in the CDF II detector. In the helicity basis, for a top-quark mass of 172.5 GeV/c2, we find a spin correlation coefficient κ=0.60±0.50 (stat)±0.16 (syst), consistent with the QCD prediction, κ≈0.40.
