Abstract

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 $p_{T}$ -ranking of the tagged $b$ -jet, the double-tag probability, the reconstructed $t + t ˉ$ invariant mass, and the lepton energy in the parent top quark rest-frame, all display interesting differences between signal and background.
