Jet measurements at DO using a KT algorithm
Abstract
DO has implemented and calibrated a KT jet algorithm for the first time in a ppbar collider. We present two results based on 1992-1996 data which were recently published: the subjet multiplicity in quark and gluon jets and the central inclusive jet cross section. The measured ratio between subjet multiplicities in gluon and quark jets is consistent with theoretical predictions and previous experimental values. NLO pQCD predictions of the KT inclusive jet cross section agree with the DO measurement, although marginally in the low pT range. We also present a preliminary measurement of thrust cross sections, which indicates the need to include higher than alpha_s^3 terms and resumation in the theoretical calculations.
