How to Observe the Interference Effects of Top quark polarizations at Tevatron

Abstract

Using a simple analytic expression for $q\bar{q},gg\to t\bar{t}\to b{W}^{+}\bar{b}{W}^{-}\to b\bar{l}{\nu }_l\bar{b}{l}^{\prime }\overline{{\nu }_{l^{\prime }}}$ with the interference effects due to the polarizations of the $t$ and $\bar{t}$, we demonstrate how the effects can be measured at Tevatron at $3\sigma$ level.
