Quark-gluon Jet Differences at Lep *
نویسنده
چکیده
A new method to identify the gluon jet in 3-jet " Y " decays of Z 0 is presented. The method is based on differences in particle multiplicity between quark jets and gluon jets, and is more effective than tagging by leptonic decay. An experimental test of the method and its application to a study of the " string effect " are proposed. Various jet-finding schemes for 3-jet events are compared.

Differences between Quark and Gluon jets as seen at LEP
The differences between quark and gluon jets are studied using LEP results on jet widths, scale dependent multiplicities, ratios of multiplicities, slopes and curvatures and fragmentation functions. It is emphasized that the observed differences stem primarily from the different quark and gluon colour factors. OPAL CR-479 31 October 2001
متن کاملScaling Violations of Quark and Gluon Jet Fragmentation Functions in Ee Annihilations
Hadron production in high energy collisions can be described by parton showers, followed by the formation of hadrons which cannot be described perturbatively. Gluon emission, the dominant process in parton showers, is proportional to the colour factor associated with the coupling of the emitted gluon to the emitter. These colour factors are CA = 3 when the emitter is a gluon and CF = 4/3 when i...

We report on an experimental comparison of the characteristics of quark-induced jets based on an analysis of jet events selected from hadronic events at c.m. energy of 60 GeV in e+e- annihilations. The triangle plot shows that the majority are two-jet events. The three-jet events are also present but not as many as two-jet events. The mean transverse momentum is larger for three-jet events th...
متن کاملReport of the Qcd Working Group
The activities of the QCD working group concentrated on improving the understanding and Monte Carlo simulation of multi-jet final states due to hard QCD processes at LEP, i.e. quark-antiquark plus multi-gluon and/or secondary quark production, with particular emphasis on four-jet final states and b-quark mass effects. Specific topics covered are: relevant developments in the main event generato...

The high hadronic event statistics collected at the Z energy (LEP I) allowed a good understanding of the QCD dynamics. The coupling constant s has been measured with several methods giving a global average s (M Z) = 0:122 0:004. The avour independence of s has been tested obtaining b s == udsc s = 0:997 0:023. Quark-gluon jet diierencies has been observed among which < n > gluon = < n > quark =...
