Further ways to distiguish single-lepton top quark signals from background at the Tevatron

Further kinematical variables are suggested, in which to compare the putative leptonic W plus 4-jet top quark signal with the QCD background. We show that the lepton rapidity asymmetry, the pT-ranking of the tagged b-jet, the double-tag probability, the reconstructed t + t invariant mass, and the lepton energy in the parent top quark rest-frame, all display interesting differences between signal and background.
