Hepnames provides a pair of LaTeX packages, heppennames and hepnicenames, providing a large set of pre-defined high energy physics particle names built with the hepparticles package. The packages are based on pennames.sty by Michel Goosens and Eric van Herwijnen. Heppennames re-implements the particle names in pennames.sty, with some additions and alterations and greater flexibility and robustness due to the hepparticles structures, which were written for this purpose. Hepnicenames provides the main non-resonant particle names from heppennames with more friendly names.
