Abstract:

The dependence of the average number of partons per clan on virtuality and rapidity variables is analytically predicted in the framework of the Generalized Simplified Parton Shower model, based on the idea that clans are genuine elementary subprocesses. The obtained results are found to be qualitatively consistent with experimental trends. This study extends previous results on the behavior of the average number of clans in virtuality and rapidity and shows how important physical quantities can be calculated analytically in a model based on essentials of QCD allowing local violations of the energy-momentum conservation law, still requiring its global validity.




Warning: This document is the result of an automated conversion from LaTeX to HTML (see "About this document..." above) for testing purposes. The major drawback found in this conversion is due to the limited resolution with which equations are converted into images: in some cases this led to blatant mistakes, as in Section 3 and 4 where a subscript capital A is turned into a capital Lambda by suppressing the horizontal stroke. Note that using larger resolution would require a very large size text which would render the reading of this document impractical. Other problems have been found in the figures section where spurious dots appear in the figures, a fact which can easily lead to some confusion.
