Abstract

We present exact tree level cross sections for the single top production process e-e+ → e-vetb at LEP 200. The results reproduce roughly those obtained earlier by using the equivalent real photon approximation and we confirm the observation that detecting a top heavier than half the c.m. energy is not feasible at LEP 200. The calculation has been performed by a new automatic Feynman amplitude generator MadGraph which produces HELAS code for the helicity amplitudes.
