This is a very preliminary overall documentation page!

HepPDT is the lowest layer in StdHepC++, an object-oriented package which modernizes and subsumes the functions of the original StdHep. Some useful features include:

• All properties (including uncertainties in the values) listed in the Review of Particle Physics.
• Access to properties assumed by various generators including Herwig, Pythia, and QQ.
• Decay mode information.
• Ability to have multiple Particle Data Tables active.
• Ability to force custom decay tables and entire decay chains.
• StdHepC++ and HepPDT can interface with the original Fortran StdHep via the HEPEVT common block and consistency in PArticleID schemes.

Documentation:

• HepPDT Introductory Users Guide
• StdHepC++ documentation.
• Design Summary for the Particle Data Table classes.
• UML Class Diagram for HepPDT.
