We present a measurement of the mass dependence of the forward-backward charge asymmetry (A(FB)) for e(+)e(-) pairs produced via an intermediate Z/gamma(*) with mass M(ee) > 40 GeV/c(2). We study the constraints on the Z-quark couplings imposed by our measurement. We analyze an integrated luminosity of 72 pb(-1) collected by the CDF-II detector in (p) over barp collisions at root s = 1.96 TeV at the Fermilab Tevatron. A comparison of the uncorrected AFB between data and standard model Monte Carlo gives good agreement with a chi(2)/DOF of 15.7/15. The couplings measurements are also consistent with standard model predictions.
