Measurement of Z-quark, Z-electron couplings and ${\sin }^2{\theta }_W$ at CDF

Abstract

The forward-backward charge asymmetry ($A_{FB}$) of $\ppbar \to e^{+}e^{-} X$ is sensitive to the vector and axial-vector couplings of the initial state quarks and final state leptons. Based on the measurement in $72p{b}^{-1}$ of CDF Run II data, we measure the coupling constants of the $Z$ boson to quarks and electron. The electroweak mixing angle, ${\sin }^2{\theta }_W$, is also measured through its relation to the coupling constants.
