Abstract
We present measurements of the forward-backward charge asymmetry in top pair production using 1.9  fb-1 of pp&#773; collisions at √s=1.96  TeV recorded with the Collider Detector at Fermilab II. Correcting for acceptance and measurement dilutions we obtain parton-level asymmetries of AFBpp&#773; =0.17±0.08 in the pp&#773; frame and AFBtt&#773; =0.24±0.14 in the tt&#773; frame. The values are consistent with the standard model expectation and disfavor exotic production mechanisms with significant negative values.
