C++ Event Record for Monte Carlo Generators
The HepMC3 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. 260 (2021) 107310, arxiv:1912.08005. It is a continuation of the HepMC2 by M. Dobbs and J.B. Hansen described in "The HepMC C++ Monte Carlo event record for High Energy Physics" (Comput. Phys. Commun. 134 (2001) 41). In version 3 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.
