DPMJET-III is a Monte Carlo event generator for hadron, photon and nuclear collisions with a several decade-long history. DPMJET is an integral part of FLUKA, a fully integrated particle physics MonteCarlo simulation package, acting as event generator for nucleus-nucleus collisions above 5 GeV/nucleon and for hadronic collisions at high energies. DPMJET-III embeds the PHOJET event generator, which is used for simulations of hadron-hadron, photon-hadron and photon-photon collisions. This and future versions of PHOJET will be distributed as part of this DPMJET package. Both codes are interfaced to Pythia 6 for hadronization.
Visit the GitHub repository for the latest version. Official releases are available for download from here.
Please use Issues for reporting bugs, questions or complaints.
The code is distributed with a copy of PYTHIA 6.4.27 and relies on its fragmentation routines. Torbjorn Sjostrand is the copyright holder of PYTHIA 6.
DPMJET is an integral part of FLUKA and FLUKA. It is responsible for simulating hadronic interactions at very high energies and nucleus-nucleus interactions from above the inelastic threshold. DPMJET's physics predictions are validated against a large body of measurements. A recent printout of the validation results and a list of physics changes between major version updates can be found here.
This and newer versions will continue supporting configuration and running though ASCII files. Instructions and options are listed in input card interface.
The Python interface is based on NumPy's f2py package, which exposes the subroutines of a Fortran library without modifications to the original source code. It runs the code at native speed with very little impact on runtime. The package chromo is the recommended user interface.
To use versioned releases, download the latest tarball from releases and unpack. To build the executables:
