Measurement of $d(\sigma)/dM$ and Forward-Backward Charge Asymmetry for High Mass Drell-Yan $e^+e^-$ Pairs from $p\bar{p}$ Collisions at $\sqrt{s} = 1.8$ TeV

We report on a measurement of the mass dependence of the forward-backward charge asymmetry, A_FB, and production cross section dsigma/dM for e+e- pairs with mass M_ee>40 GeV/c2. The data sample consists of 108 pb-1 of p-pbar collisions at sqrt(s)=1.8 TeV taken by the Collider Detector at Fermilab during 1992-1995. The measured asymmetry and dsigma/dM are compared with the predictions of the Standard Model and a model with an extra Z' gauge boson.
