Forward-backward charge asymmetry of electron Paris above the Z(0) pole

We present a measurement of the forward-backward charge asymmetry of the process p p̄ → Z0/γ + X, Z0/γr → e+ e- at Mee > Mz, 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 Mee...

Sumari:We present a measurement of the forward-backward charge asymmetry of the process p p̄ → Z0/γ + X, Z0/γr → e+ e- at Mee > Mz, 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 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.
