Leptoquark and R-Parity Violating SUSY Processes

Pair production of leptoquarks at future e+e- linear colliders is investigated for center-of-mass energies of 500 GeV and 800 GeV and an integrated luminosity of 500 fb^-1. Based on a Monte Carlo simulation we estimate the event rates for signal as well as background processes and evaluate the discovery potential. As an example of virtual effects we consider deviations from standard model predictions due to R-parity violating sneutrino exchange in purely leptonic processes.
