A precision measurement of the top quark mass m_t is obtained
using a sample of t anti-t events from p anti-p 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 b 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 m_t and a parameter
DJES to calibrate the jet energy scale /in situ/. Using a total of 1087
events, a value of m_t 173.0 +/- 1.2 GeV/c2 is measured.
