    abstract = "We report a measurement of the top quark mass, m(t), obtained from
p(p)over bar collisions at root s=1.96 TeV at the Fermilab Tevatron
using the CDF II detector. We analyze a sample corresponding to an
integrated luminosity of 1.9 fb(-1). We select events with an electron
or muon, large missing transverse energy, and exactly four high-energy
jets in the central region of the detector, at least one of which is
tagged as coming from a b quark. We calculate a signal likelihood using
a matrix element integration method, where the matrix element is
modified by using effective propagators to take into account assumptions
on event kinematics. Our event likelihood is a function of m(t) and a
parameter JES (jet energy scale) that determines in situ the calibration
of the jet energies. We use a neural network discriminant to distinguish
signal from background events. We also apply a cut on the peak value of
each event likelihood curve to reduce the contribution of background and
badly reconstructed events. Using the 318 events that pass all selection
criteria, we find m(t)=172.7 +/- 1.8(stat+JES)+/- 1.2(syst) GeV/c(2)."
