At the Tevatron Collider, it is possible to create single top quarks in the final state via either off mass shell W* production, or the W-gluon fusion process. The Standard Model predicts a cross section of only 2.4 pb, and the backgrounds are significantly larger, which makes the Neural Networks approach suitable for a single top search. A-priori and a-posteriori results on single top production are presented.
