Tim Head
TL;DR
This paper discusses measurements of top and anti-top quark spin correlations at the Tevatron, using data from CDF and D0, confirming consistency with Standard Model predictions.
Contribution
It presents the first measurements of top quark spin correlations at the Tevatron using up to 4.3 fb^-1 of data, in dileptonic and semileptonic channels.
Findings
Measured spin correlation parameter C aligns with Standard Model.
Used data from CDF and D0 detectors at 1.96 TeV.
Analyzed dileptonic and semileptonic final states.
Abstract
Recent measurements of the correlation between the spin of the top and the spin of the anti-top quark produced in proton anti-proton scattering at a centre of mass energy of 1.96 TeV by the CDF and D0 collaborations are discussed. Using up to 4.3 fb^-1 of data taken with the CDF and D0 detectors the spin correlation parameter C, the degree to which the spins are correlated, is measured in dileptonic and semileptonic final states. The measurements are found to be in agreement with Standard Model predictions.
