Abstract: We present an optimized and physically motivated method for separating top quark signal events from background events at the Fermilab Tevatron. For the top quark signal tt\ifmmode\bar\else\textasciimacron\fi{}\ensuremath{\rightarrow}e/\ensuremath{\mu}+4 jets, we show how to reject all but 25% of the background in a data sample while retaining 83% of the signal, without introducing bias into the subsequent mass measurement. The technique used is the binary decision tree. Combining this highly efficient procedure for signal identification with a novel algorithm for top quark reconstruction, we propose a powerful new way to measure the top quark mass.
