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.
