The Pluto Event Generator — •Ingo Fröhlich1 and Romain Holzmann2 — 1Institut für Kernphysik, 60438 Frankfurt am Main — 2Gesellschaft für Schwerionenphysik, 64291 Darmstadt
Pluto is a Monte-Carlo event generator designed for hadronic interactions from close-to-threshold to intermediate energies, as well as for studies of heavy ion reactions. The package is entirely based on Root, without the need of additional packages, and uses the embedded C++ interpreter of root to control the event production.
The package includes realistic models of resonance production by using mass-dependent Breit-Wigner sampling. The calculation of partial and total widths for resonances is taken into account. Particular attention is paid to the electromagnetic decays, motivated by the physics program of HADES.
For elementary reactions, angular distributions (e.g. for the primary meson emission) can be attached by the user in a very simple way as well as multi-particle correlations. Hand-made models (which may change all decay parameters) can be included by the user without recompliation using the CINT interpreter.
This contribution gives an overview of the technical implementation of the framework and presents examples of the included physics.
