Book excerpt: Jet shapes at (square root)s = 1.8 TeV have been measured by CDF at the Fermilab Tevatron Collider. The jet shape is mainly formed by parton emission before hadronization. The jet shapes may also be used to differ between quark and gluon jets. Two approaches are tried. Jet shape variables are input to a feed forward neural network trained on QCD Monte Carlos. We observe a variation of the quark content of jets as a function of jet transverse energy. The second approach consists of constructing a likelihood function, based on Monte Carlo predictions, with the Mellin moments of the momentum of charged tracks in jets. Differences are found between gluon-like jets in 2-jet events and quark-like jets in photon-jet events.

Book excerpt: In this paper, the most recent results on jet fragmentation obtained at the Collider Detector at Fermilab Tevatron are presented. The multiplicity and momentum distribution of charged particles inside jets in dijet events are compared to the predictions of the Modified Leading Log Approximation complemented with the hypothesis of Local Parton-Hadron Duality. Values for the two parameters of the model are extracted, the cut-off scale Q{sub eff} = 230 ± 40 MeV and the rate of parton-to-hadron conversions K{sub LPHD}{sup charged} = 0.56 ± 0.10. A fit of the data for the ratio of multiplicities in gluon and quark jets r, where r is treated as a free parameter, results in r = 1.9 ± 0.5. Also, we compare the charged particle multiplicities in dijet and [gamma]-jet events. The comparison allows for an extraction of a model-independent ratio of multiplicities in gluon and quark jets. We report r = N{sub g}/N{sub q} = 1.61 ± 0.11(stat) ± 0.28(syst) for E{sub jet} = 40 GeV.

Download or read book A Study of Quark and Gluon Jets and of the Long Distance QCD Force Field at the Z[sup 0]. written by and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum Chromodynamics (QCD) is widely accepted as the correct theory of the strong nuclear force in elementary particle physics. The precision to which QCD has been tested is relatively limited, however, compared to the precision to which other interactions such as the electro-weak one have been tested. In part, this is because the large value of the QCD coupling constant, [alpha][sub s], renders theoretical calculations based on perturbation theory relatively imprecise. The confinement of quarks and gluons inside hadrons also leads to uncertainty because the theoretical predictions cannot, in general, be tested directly against the experimental measurements but are subject to hadronization corrections. From an experimental standpoint, it has proven difficult to isolate gluon jets inside multi-jet events in an unbiased manner so as to determine gluon jet properties using model independent methods. Basic quark-gluon interactions such as the four-jet matrix element in e[sup+]e[sup -] annihilations have been relatively untested due to the lack of a data sample with sufficient statistics. Perturbation theory has essentially nothing to say about the properties of the hadronization process itself. It is for these reasons that QCD has remained relatively untested.

Book excerpt: We suggest a procedure, based on the kinematics of qg-scattering in high-p/sub T/ events, whereby it is possible to obtain enriched samples of quark and gluon jets. At SppS energies this could be used to indicate whether quark and gluon jet fragmentation agree or not. At higher energies the application would rather be to study the differences in the parton cascades, i.e. jet substructure.
