Review of Particle Physics

Abstract

The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,062 new measurements from 721 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark photons, etc. All the particle properties and search limits are listed in Summary Tables. We also give numerous tables, figures, formulae, and reviews of topics such as Higgs Boson Physics, Supersymmetry, Grand Unified Theories, Neutrino Mixing, Dark Energy, Dark Matter, Cosmology, Particle Detectors, Colliders, Probability and Statistics. Among the 117 reviews are many that are new or heavily revised, including those on Pentaquarks and Inflation.The complete Review is published online in a journal and on the website of the Particle Data Group (http://pdg.lbl.gov). The printed PDG Book contains the Summary Tables and all review articles but no longer includes the detailed tables from the Particle Listings. A Booklet with the Summary Tables and abbreviated versions of some of the review articles is also available.Contents , Contributors, Highlights and Table of ContentsAcrobat PDF (150 KB) IntroductionAcrobat PDF (456 KB) Particle Physics Summary TablesGauge and Higgs bosonsAcrobat PDF (155 KB)LeptonsAcrobat PDF (134 KB)QuarksAcrobat PDF (84 KB)MesonsAcrobat PDF (871 KB)BaryonsAcrobat PDF (300 KB)Searches (Supersymmetry, Compositeness, etc.)Acrobat PDF (91 KB)Tests of conservation lawsAcrobat PDF (330 KB) Reviews, Tables, and PlotsDetailed contents for this sectionAcrobat PDF (37 KB)Constants, Units, Atomic and Nuclear PropertiesAcrobat PDF (278 KB)Standard Model and Related TopicsAcrobat PDF (7.3 MB)Astrophysics and CosmologyAcrobat PDF (2.7 MB)Experimental Methods and CollidersAcrobat PDF (3.8 MB)Mathematical Tools or Statistics, Monte Carlo, Group Theory Acrobat PDF (1.3 MB)Kinematics, Cross-Section Formulae, and PlotsAcrobat PDF (3.9 MB) Particle ListingsIllustrative key and abbreviationsAcrobat PDF (235 KB)Gauge and Higgs bosonsAcrobat PDF (2 MB)LeptonsAcrobat PDF (1.5 MB)QuarksAcrobat PDF (1.2 MB)Mesons: Light unflavored and strangeAcrobat PDF (4 MB)Mesons: Charmed and bottomAcrobat PDF (7.4 MB)Mesons: OtherAcrobat PDF (3.1 MB)BaryonsAcrobat PDF (3.97 MB)Miscellaneous searchesAcrobat PDF (2.4 MB) IndexAcrobat PDF (160 KB)
