Hadronization Effects in the Strong Interaction
(1998) Abstract
 Different hadronization effects in high energy interactions are investigated. The framework is the Lund model for the strong interaction.
A model for baryon production in jet fragmentation is presented and extended to baryon remnant fragmentation in deep inelastic scattering and hadronhadron collisions.
Observables designed to probe hadronization effects on p<sub>t</sub> correlations are shown to be sensitive to model assumptions, provided a strong twojet cut is imposed on the data sample. A cut on highp<sub>t</sub> jets also improves the similarity between quark jets in deep inelastic scattering and e<sup>+</sup>e<sup></sup> annihilation, and is...

A model for baryon production in jet fragmentation is presented and extended to baryon remnant fragmentation in deep inelastic scattering and hadronhadron collisions.
Observables designed to probe hadronization effects on p<sub>t</sub> correlations are shown to be sensitive to model assumptions, provided a strong twojet cut is imposed on the data sample. A cut on highp<sub>t</sub> jets also improves the similarity between quark jets in deep inelastic scattering and e<sup>+</sup>e<sup></sup> annihilation, and is thus suitable for an investigation of quark fragmentation universality.
The scale dependencies in jets are discussed and emphasis is put on the virtuality dependence rarely considered in theoretical calculations. Jet definitions corresponding to the theoretically considered jets are presented.
The ratio of multiplicities in quark and gluon jets are calculated within the framework of the Colour Dipole cascade. Energy conservation together with preconfinement implies a numerically large NNLO correction, which gives a result in agreement with data. (Less)
