We present a measurement of the forward-backward charge asymmetry of the process p (p) over bar --> Z(0)/gamma + X, Z(0)/gamma --> e(+)e(-) at M(ee) > M(Z), using 110 pb(-1) of data at root 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/c(2), and 0.070 +/- 0.016 in the region 75 < M(ee) < 105 GeV/c(2). These results are consistent with the standard model values of 0.528 +/- 0.009 and 0.052 +/- 0.002, respectively.

Abstract

We present a measurement of the forward-backward charge asymmetry of the process p (p) over bar --> Z(0)/gamma + X, Z(0)/gamma --> e(+)e(-) at M(ee) > M(Z), using 110 pb(-1) of data at root 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/c(2), and 0.070 +/- 0.016 in the region 75 < M(ee) < 105 GeV/c(2). These results are consistent with the standard model values of 0.528 +/- 0.009 and 0.052 +/- 0.002, respectively.
