Abstract [en]

We measure the correlation between the spin of the top quark and the spin of the anti-top quark in final states produced in collisions at a center of mass energy , where is an electron or muon. The data correspond to an integrated luminosity of 5.4 fb−1 and were collected with the D0 detector at the Fermilab Tevatron collider. The correlation is extracted from the angles of the two leptons in the t and rest frames, yielding a correlation strength , in agreement with the NLO QCD prediction within two standard deviations, but also in agreement with the no correlation hypothesis.
