Top Quark Mass Measurement in the Lepton+Jets Channel at CDF using a Template Method

We present a measurement of the top quark mass in top quark pair production events decaying into the lepton+jets channel. The measurement uses proton-antiproton collision data at $\sqrt{s}=1.96$ TeV collected by CDF Run II detector at Fermilab. We reconstruct a top quark mass in each event by using kinematic constraints on the pair of top quarks and the mass of the hadronic decaying W boson to calibrate the energy response of the detector. We determine the top quark mass and an \textit{in situ} measurement of the jet energy scale from a simultaneous likelihood fit to the reconstructed top quark mass and W boson invariant mass distributions in the data to distributions from Monte Carlo simulation.
