Inclusive Jet Cross Section
and Dijet Cross Section
preliminary results from March 2004
We present preliminary measurements of the inclusive jet cross section
as a function of the transverse jet momentum pT
and the dijet cross section
as a function of the invariant dijet mass Mjj.
The dijet cross section is measured in the
central region of rapidity |yjet|<0.5.
The measurement of the inclusive jet cross section
extends over a range of rapidities up to
|yjet|<2.4.
Jets are reconstructed by an iterative cone algorithm
with cone radius Rcone = 0.7.
A good agreement between NLO pQCD and data is found.
