Particle Data Group

The Particle Data Group (PDG) is an international collaboration of particle physicists that compiles and reanalyzes published results related to the properties of particles and fundamental interactions. It also publishes reviews of theoretical results that are phenomenologically relevant, including those in related fields such as cosmology. 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 World Wide Web.

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 high energy physics institutions, which is now discontinued.^[1] PDG also further maintains the standard numbering scheme for particles in event generators, in association with the event generator authors.
