We examine the effects of the R parity odd renormalizable interactions onflavor changing rates and CP violation asymmetries in the production offermion-antifermion pairs at $e^-- e^+$ leptonic colliders. The producedfermions may be leptons, down-quarks or up-quarks, and the center of massenergies may range from the Z-boson pole up to $ 1000$ GeV. Off the Z-bosonpole, the flavor changing rates are controlled by tree level amplitudes and theCP asymmetries by interference terms between tree and loop level amplitudes. Atthe Z-boson pole, both observables involve loop amplitudes. The lepton numberviolating interactions, associated with the coupling constants, $\l_{ijk},\l'_{ijk}$, are only taken into account. The consideration of loop amplitudesis restricted to the photon and Z-boson vertex corrections. We briefly reviewflavor violation physics at colliders. We present numerical results using asingle, species and family independent, mass parameter, $\tilde m$, for all thescalar superpartners and considering simple assumptions for the familydependence of the R parity odd coupling constants.Comment: Latex File. 23 pages. 4 postscript figures. 1 table.
