The DIPSY Monte Carlo
Welcome to DIPSY
DIPSY (Dipoles in Impact Parameter Space and Rapidity (Y)) is a Monte Carlo
event generator for high energy particle physics, primarily developed for
min. bias in pp collisions and heavy ion physics. The generator is developed
in
Lund, based on
the
ThePEG framework for MC event
generators.
On this page we collect references, comparison plots, figures, presentations
etc. that could be of interest in connection with the DIPSY generator.
Comparison plots
Here we show a number of figures comparing DIPSY predictions to data. The
figures are created with the
Rivet
package for generator validation, and the analysis name refer to the
corresponding Rivet analysis. It is possible to see performance of many other
generators at the
MCplots page. To
do a direct comparison with other generators, you can download histogram files in the .yoda
format.
Minimum bias comparison
A range of plots comparing the DIPSY program with experimental
data for minimum bias and underlying events. Some of these were included in
the paper axXiv:11mmnnnn and but most could not be included due to lack of
space.
Hadronisation
A range of plots comparing the DIPSY program with rope hadronisation with data
and Pythia v. 8.14. Some were included in the paper arXiv:14xxxxx, but most
could not be included either due to lack of space, or because the analysis
itself were too preliminary.
Rope hadronization
DIPSY implements the rope hadronization model, as described in
this paper . The model affects
mainly the hadrochemistry of final states. This model is currently being implemented
in the
Pythia 8
event generator. The temporary implementation can be downloaded and run together
with Pythia 8.226 as a plugin.
