  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.
