Parton Correlations in High Energy ProtonProton Scattering
Abstract
In this thesis we will use the Monte Carlo (MC) event generator DIPSY to
study correlations in protonproton scattering. DIPSY uses a modified
version of the Mueller dipole model to dynamically create the wave
function of a proton, or at least a very simple approximation thereof.
We will look at the correlation between the inverse dipole sizes and the
number of dipoles, or the number of subscatterings, to see the effects
screening. We will also look at some correlation that may give a dynamical
explanation to some of the assumptions made in the multiple interaction
model implemented in the PYTHIA MC. These assumptions include, the
distribution of the number of subscatterings both at fixed impact
parameter and as an average aver all impact parameters, and the shape of
the overlap (of the wave functions) of two colliding protons.
The DIPSY program is still under development, and the results presented
here should be considered preliminary.
