   Abstract:
   We present measurements of the forward-backward charge asymmetry in top pair production using 1.9 fb-1 of $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV recorded with the Collider Detector at Fermilab II. Correcting for acceptance and measurement dilutions we obtain parton-level asymmetries of AFB$p\bar{p}$=0.17\pm 0.08 in the $p\bar{p}$ frame and AFB$t\bar{t}$=0.24+/-0.14 in the $t\bar{t}$ frame. The values are consistent with the standard model expectation and disfavor exotic production mechanisms with significant negative values.
