Abstract
|
|
|
|
| We present measurements of the forward-backward charge asymmetry in top pair production using 1.9 fb-1 of pp̅ 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 AFBpp̅ =0.17±0.08 in the pp̅ frame and AFBtt̅ =0.24±0.14 in the tt̅ frame. The values are consistent with the standard model expectation and disfavor exotic production mechanisms with significant negative values. |
