Description
We measure the correlation between the spin of the top quark and the
spin of the anti-top quark in $t\bar{t} \rightarrow W^{+}bW^{-}\bar{b}$
final states produced in $p\bar{p}$ collisions at a center of mass energy $\sqrt{s}=1.96$~TeV,
using data collected with the D0 detector at the Fermilab Tevatron collider.
The correlation is extracted using a double differential angular distribution
and a novel technique using matrix element integration is used to increase
the sensitivity of the result, Measurements are performed in both the
dilepton and lepton+jets final states.
