- Jet shapes at [radical]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.
