HepMC3 event record library
|
The HepMC package is an object oriented, C++ event record for High Energy Physics Monte Carlo generators and simulation, described in A. Buckley et al., The HepMC3 Event Record Library for Monte Carlo Event Generators (Comput. Phys. Commun. (2020), in press) InSpire record
The original code was written by M. Dobbs and J.B. Hansen, The HepMC C++ Monte Carlo event record for High Energy Physics (Comput. Phys. Commun. 134 (2001) 41). Since the first implementation, the package has undergone several modifications and in particular, the latest HepMC3 series is a completely new re-write using currently available C++11 techniques, and have out-of-the-box interfaces for the widely used in HEP community ROOT and Python.
Further documentation that might be useful for the users of HepMC3 can be found in the following documents:
The current development effort is concentrated on the HepMC3 series. Users are encouraged to integrate that version in their applications and to provide any feedback they may have. Visit the CERN GitLab repository https://gitlab.cern.ch/hepmc/HepMC3 for more information.
The HepMC2 series development has been essentially stopped and in particular HepMC2.06.x (with the latest being 2.06.11) versions are frozen. Some of the new features of HepMC3 series are now also available in HepMC2.07.x versions, but this should be regarded (for those who need it) as an intermediate step before migrating to HepMC3. Since HepMC3 version 3.1 both HepMC2 and HepMC3 can be installed in the same prefix simultaneously. Finally, HepMC1 series is by now fully deprecated.
