A measurement of the forward-backward charge asymmetry in top-antitop (tt-bar) pair production in proton-antiproton (pp-bar) collisions is presented. The asymmetry is measured for different jet multiplicities in the lepton+jets final state on 0.9 fb{sup -1} of data collected by the DOe experiment at the Fermilab Tevatron Collider. The result is sensitive to new physics, which is demonstrated by setting an upper limit on tt-bar production via heavy neutral gauge bosons (Z')
