Abstract

This biennial Review summarizes much of particle physics. Using data from
previous editions, plus 2158 new measurements from 551 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 topics such as the Standard
Model, particle detectors, probability, and statistics. Among the 108 reviews
are many that are new or heavily revised including those on neutrino mass,
mixing, and oscillations, QCD, top quark, CKM quark-mixing matrix, Vud &
Vus , Vcb & Vub, fragmentation functions, particle detectors for accelerator and
non-accelerator physics, magnetic monopoles, cosmological parameters, and
big bang cosmology.
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 reviews
(and errata) are also available on the Particle Data Group website: pdg.lbl.gov.
