| Research Abstract |
Using 195 top anti-top pairs found in the collision data taken at the CDF experiment conducted with TEVATRON, proton anti-proton collider at Fermi National Accelerator Laboratory, we performed a measurement of the correlation between the spin polarizations of the top quark and the anti-top quark, and presented the results on a web page of the CDF experiment, at JPS meeting, and so on. This is the first result on measurements of the spin correlations in the top quark pair production since RUN2 experiments at TEVATRON started in 2000, and thus regarded as the important milestone for the study on the top quark pair production mechanism taking advantage of top quark spins.
