Abstract
A precision measurement of the top quark mass is obtained using a sample of events from collisions at the Fermilab Tevatron with the CDF II detector. Selected events require an electron or muon, large missing transverse energy, and exactly four high-energy jets, at least one of which is tagged as coming from a quark. A likelihood is calculated using a matrix element method with quasi-Monte Carlo integration taking into account finite detector resolution and jet mass effects. The event likelihood is a function of and a parameter used to calibrate the jet energy scale in situ. Using a total of 1087 events in of integrated luminosity, a value of is measured.
