Abstract
Single-lepton plus jets signals from production at hadron colliders generally give more spherically symmetrical events than the principal backgrounds from production. We show that sphericity and aplanarity criteria, applied to lepton plus neutrino plus four jet final states at the Fermilab Tevatron collider, help to discriminate; they can be used either to validate an eventual top signal or simply to reduce background. An alternative circularity criterion in the transverse plane is less successful.
