[en] The biennial review summarizes much of particle physics. Using data from previous editions, plus 2000 new measurements from 610 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We also summarize searches for hypothetical particles such as Higgs bosons, heavy neutrinos, and supersymmetric particles. All the particle properties and search limits are listed in summary tables. We also give numerous tables, figures, formulae, and reviews of topic 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 sections of this full reviews. All tables, listings, and reviews (and errata) are also available on the particle data group website
