| Abstract |
We present the first measurement of two-particle momentum correlations in jets produced in p-pbar collisions
at sqrt{s}=1.96 TeV. Results are obtained for charged particles within a restricted cone
with an opening angle of 0.5 radians around the jet axis and for events with dijet masses between 66 and 563 GeV/c^2.
A comparison of the experimental data to theoretical predictions obtained for partons within the framework of
resummed perturbative QCD in the next-to-leading log approximation (NLLA) shows that the parton momentum correlations
survive the hadronization stage of jet fragmentation, giving further support to the hypothesis of local parton-hadron duality.
The extracted value of the NLLA parton shower cutoff scale Q_eff is found to be (1.4^{+0.9}_{-0.7}) x 100 MeV.
