Parity violation in top quark pair production at the Fermilab Tevatron collider

The leading weak corrections to the production of top quark pairs via qq → tt in pp collisions are evaluated. The chromoanapole form factor of the top quark and effects of parity violation are studied in the Standard Model (SM) and the Minimal Supersymmetric Model (MSSM). The parity violation effect in qq → g → tt from the SM weak corrections is found to be very small. In the MSSM, the effects of parity violation can be enhanced for tan β≜ν2ν1>mtmb.
