Description
We report on the first measurement of the angular distribution of final state lepton and also the forward and backward asymmetry (Afb) which is sensitive to Weinberg angle in $p\bar{p} \to \gamma^{*}/Z \to \ell^{+}\ell^{-} + X$ events produced at $\sqrt{s}=1.96 TeV$. The data sample collected by the CDF II detector.
The angular distributions are studied as a function of the transverse momentum of the lepton pair. The Lam-Tung relation which is only valid for a spin-1 description of the gluon is also tested.
