Abstract:
We report on a study of jet shapes in inclusive jet production in ppˉp \bar{p} collisions at s=1.96TeV\sqrt{s} = 1.96 {\rm TeV} using the upgraded Collider Detector at Fermilab in Run II (CDF II) based on an integrated luminosity of 170pb1170 \rm pb^{-1}. Measurements are carried out on jets with rapidity 0.1<Yjet<0.70.1 < |Y^{\rm jet}| < 0.7 and transverse momentum 37 GeV/c <PTjet<380< P_T^{\rm jet} < 380 GeV/c. The jets have been corrected to the hadron level. The measured jet shapes are compared to leading-order QCD parton-shower Monte Carlo predictions as implemented in the PYTHIA and HERWIG programs. PYTHIA, tuned to describe the underlying event as measured in CDF Run I, provides a better description of the measured jet shapes than does PYTHIA or HERWIG with their default parameters.
