Abstract/Summary:
We present a measurement of the Z boson forward-backward charge asymmetry of the process pp¯ → gamma*/ Z + X → e+ e- + X, where the mass of the intermediate gamma*/ Z has invariant mass above 30 GeV/c2. The measurement uses 0.36 fb-1 of Run II data. The method of matrix inversion is used to correct for the distortion in the measurement caused by the detector resolution and photon radiation in the final state. A search for a new physics based upon the forward-backward asymmetry is also presented.
