Jet algorithms and top quark mass measurement

Mass measurements of objects that decay into hadronic jets, such as the top quark, are shown to be improved by using a variant of the kt jet algorithm in place of standard cone algorithms. The possibility and importance of better estimating the neutrino component in tagged b jets is demonstrated. These techniques will also be useful in the search for Higgs boson→b bar b. copyright 1997 The American Physical Society
