CDF MEASUREMENT OF THE TOP QUARK MASS IN THE LEPTON+JETS CHANNEL USING THE MULTIVARIATE TEMPLATE METHOD.

We measure the mass of the top quark using 162 pb-1 of data collected by the CDF experiment at the Fermilab Tevatron in Run II. The decay chain $t{\bar t} \to bq{\bar q}{\bar b}l\nu$ is studied using a novel technique called the Multivariate Template Method (MTM). Using this technique we obtain a result of $M_{top} = 179.6^{+6.4}_{-6.3}({\rm stat.}) \pm 6.8({\rm syst.})\ {\rm GeV}/c^2$ for the top quark. [ABSTRACT FROM AUTHOR]
