Particle Data Group

The Particle Data Group (PDG) is an international collaboration of <a href="/facts/Particle_physics/YgIuyj2t">particle physicists</a> that compiles and reanalyzes published results related to the properties of <a href="/facts/List_of_particles/FwR0Ab6u">particles</a> and <a href="/facts/Fundamental_interaction/WrFEJaFl">fundamental interactions</a>. It also publishes reviews of theoretical results that are phenomenologically relevant, including those in related fields such as <a href="/facts/Cosmology/yM19zM7Y">cosmology</a>. The PDG currently publishes the Review of Particle Physics and its pocket version, the Particle Physics Booklet, which are printed biennially as books, and updated annually via the <a href="/facts/World_Wide_Web/wvnTrWFq">World Wide Web</a>.
In previous years, the PDG has published the Pocket Diary for Physicists, a calendar with the dates of key international conferences and contact information of major <a href="/facts/High_energy_physics/YgIuyj2t">high energy physics</a> institutions, which is now discontinued. PDG also further maintains the standard numbering scheme for particles in <a href="/facts/Event_generator/dg8hCYfr">event generators</a>, in association with the event generator authors.
