Abstract
We report a measurement of the top-quark mass, , in the dilepton decay channel of using an integrated luminosity of of collisions collected with the CDF II detector. We apply a method that convolutes a leading-order matrix element with detector resolution functions to form event-by-event likelihoods; we have enhanced the leading-order description to describe the effects of initial-state radiation. The joint likelihood is the product of the likelihoods from 78 candidate events in this sample, which yields a measurement of , the most precise measurement of in the dilepton channel.
