R-parity violation and top quark polarization at the Fermilab Tevatron collider - art. no. 114041

The lepton or baryon number violating top quark interactions in the supersy mmetric standard model with R-parity violation contribute to the process d (d) over bar-->t (t) over bar at the tree level via the t- or u-channel sfe rmion exchange; Since these interactions are chiral, they induce polarizati on to the top quark in the t (t) over bar events at hadron colliders, We sh ow in this article that the polarization can be a useful observable for pro bing these interactions at the upgraded Fermilab Tevatron collider, because the polarization is expected to be very small in the standard model.
