Abstract

We present a measurement of the forward-backward charge asymmetry of the process pp^¯ → Z⁰/γ + X, Z⁰/γ → e⁺e⁻ at M_ee > M_Z using 110 pb⁻¹ of data at √ s = 1.8 TeV collected at the Collider Detector at Fermilab. The measured charge asymmetries are 0.43 ± 0.10 in the invariant mass region M_ee > 105 GeV/c², and 0.070 ± 0.016 in the region 75 < M_ee < 105 GeV/c². These results are consistent with the standard model values of 0.528 ± 0.009 and 0.052 ± 0.002, respectively.
