TheParticle Data Group (PDG) is an international collaboration ofparticle physicists that compiles and reanalyzes published results related to the properties ofparticles andfundamental interactions. It also publishes reviews of theoretical results that are phenomenologically relevant, including those in related fields such ascosmology. The PDG currently publishes theReview of Particle Physics and its pocket version, theParticle Physics Booklet, which are printed biennially as books, and updated annually via theWorld Wide Web.
In previous years, the PDG has published thePocket Diary for Physicists, a calendar with the dates of key international conferences and contact information of majorhigh energy physics institutions, which is now discontinued.[1] PDG also further maintains the standard numbering scheme for particles inevent generators, in association with the event generator authors.
TheReview of Particle Physics[2] (formerlyReview of Particle Properties,Data on Particles and Resonant States, andData on Elementary Particles and Resonant States) is a voluminous, 1,200+ page reference work which summarizes particle properties and reviews the current status ofelementary particle physics,general relativity andBig Bang cosmology. Usually singled out forcitation analysis, it is currently the most cited article inhigh energy physics, being cited more than 2,000 times annually in the scientific literature (as of 2009[update]).[3][4]
The Review is currently divided into three sections:
A condensed version of theReview, with theSummary Tables, a significantly shortenedReviews, Tables and Plots, and without theParticle Listings, is available as a 300-page, pocket-sizedParticle Physics Booklet.
The history of theReview of Particle Physics can be traced back to the 1957 articleHyperons and Heavy Mesons (Systematics and Decay) byMurray Gell-Mann andArthur H. Rosenfeld,[5] and the unpublished update tables for its data with the titleData for Elementary Particle Physics (University of California Radiation LaboratoryTechnical Report UCRL-8030)[6][7] that were circulated before the actual publication of the original article. In 1963,Matts Roos independently published a compilationData on Elementary Particles and Resonant States.[8][9] On his suggestion, the two publications were merged a year later into the 1964Data on Elementary Particles and Resonant States.
The publication underwent three renamings thereafter: in 1965 toData on Particles and Resonant States, in 1970 toReview of Particle Properties, and in 1996 to the present formReview of Particle Physics. Starting in 1972, theReview no longer appeared exclusively inReviews of Modern Physics, but also inPhysics Letters B,European Physical Journal C,Journal of Physics G,Physical Review D, andChinese Physics C (depending on the year).
