production release: 2.06.08

Documentation is available from the Homepage link.

Discussions about future HepMC releases are held within the context of the LCG simulation project (-unavailable-).

The HepMC package is an object oriented event record written in C++ for High Energy Physics Monte Carlo Generators. Many extensions from HEPEVT, the Fortran HEP standard, are supported: the number of entries is unlimited, spin density matrices can be stored with each vertex, flow patterns (such as color) can be stored and traced, integers representing random number generator states can be stored, and an arbitrary number of event weights can be included. Particles and vertices are kept separate in a graph structure, physically similar to a physics event. The added information supports the modularisation of event generators. The package has been kept as simple as possible with minimal internal/external dependencies. Event information is accessed by means of iterators supplied with the package.

HepMC 2.06.08 is now available.

GenEvent has a new method, define_units() which can be used when the units in this event do not match the default units. Define_units() does not convert momenta or lenght.

In addition, fix a bug so that IO_GenEvent::use_input_units() is properly consulted for all input cases. ...
