Recombination Methods for Jets in p\pbar Collisions

Abstract

A jet algorithm must specify how to (re-)combine different partons or towers into a single four-vector. Various recombination schemes have been used experimentally to examine the transverse energy profile of jets in hadron colliders. Generally, the data is insensitive to which scheme is used. However, we argue that the recombination scheme previously used by the \DO\ collaboration is expected to have large perturbative corrections and should not be used for the purposes of making a quantitative comparison with fixed-order perturbation theory.Comment: 11 pages in PLAIN TeX with 4 uuencoded figures embedded with epsf.te
