abstract
We present a measurement of the forward-backward charge asymmetry of the process pp Z0/ + X, Z0/ e+e at Mee > MZ using 110 pb1 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 Mee > 105 GeV/c2, and 0.070 0.016 in the region 75 < Mee < 105 GeV/c2. These results are consistent with the standard model values of 0.528 0.009 and 0.052 0.002, respectively. 1996 The American Physical Society.
