Abstract
We present a new method for modeling the hadronic recoil in W -} lv events produced at hadron colliders. The recoil is chosen from a library of recoils in Z -} ll data events and overlaid on a simulated W -} lv event.
Implementation of this method requires that the data recoil library describe the proper-ties of the measured recoil as a function of the true, rather than the measured, transverse momentum of the boson. We address this issue using a multidimensional Bayesian unfolding technique.
We estimate the statistical and systematic uncertainties from this method for the W boson mass and width measurements assuming 1 fb(-1) of data from the Fermilab Tevatron. The uncertainties are found to be small and comparable to those of a more traditional parameterized recoil model.
