Review of Particle Physics

This biennial Review summarizes much of Particle Physics. Using data from p revious editions, plus 2000 new measurements from 610 papers, we list, eval uate, and average measured properties of gauge bosons, leptons, quarks, mes ons, and baryons. We also summarize searches for hypothetical particles suc h as Higgs bosons, heavy neutrinos, and supersymmetric particles. All the p article properties and search limits are listed in Summary Tables. We also give numerous tables, figures, formulae, and reviews of topics such as the Standard Model, particle detectors, probability, and statistics. A booklet is available containing the Summary Tables and abbreviated versions of some of the other sections of this full Review. All tables, listings, and revie ws (and errata) are also available on the Particle Data Group website: http ://pdg.lbl.gov.
