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.

This biennial Review summarizes much of Particle Physics. Using data from previous editions, plus 2205 new measurements from 667 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. This edition features expanded coverage of CP violation in B mesons and of neutrino oscillations. For the first time we cover searches for evidence of extra dimensions (both in the particle listings and in a new review). Another new review is on Grand Unified Theories.

Abstract

We present a high statistics measurement of the branching ratio for the decay τ-→π-μτ using data obtained with the Mark II detector at the SLAC e+e- storage ring SPEAR. We have used events from the center-of-mass energy region 3.52 to 6.7 GeV to determine that B(τ-→π-μτ)=0.117±0.004±0.018. From electron-muon events in the same data sample, we have determined that B(τ-→π-μτ) B(τ-→e--μeμτ)=0.66±0.03±0.11. We present measurements of the mass and spin of the τ and the mass of the τ neutrino based, for the first time, on a hadronic decay mode of the τ. © 1982.

Abstract

A high-statistics study of decays into baryon final states has been done with the Mark II detector at SPEAR. A detailed test of baryon-antibaryon decay modes is presented. Substantial resonance formation is observed in multibody decays of the involving baryons. Branching ratios for a large number of decay modes are given, including the radiative decay pp. The flavor-SU(3)-forbidden decays (1385)+charge conjugate are observed with substantial branching ratios. © 1984 The American Physical Society.

Abstract

We present results of a detailed analysis of inclusive direct photon production at the (3095). The direct-photon momentum distribution for x>0.4 is presented and compared with the leading-order quantum-chromodynamic prediction. The total production rate is found to be consistent with theoretical expectations, but the observed momentum distribution is considerably softer. Results of an analysis of some inclusive properties of the hadronic system recoiling against the direct photon are presented. The mean charged-particle and Ks multiplicities are presented as functions of the invariant mass of the hadronic system. These data agree well with the corresponding mean multiplicities measured in e+e- annihilations at center-of-mass energies comparable to the invariant mass of the hadronic system. © 1981 The American Physical Society.

Abstract

Searches for 12 neutrinoless decay modes of the which violate lepton-number conservation have been made using the reaction e+e-+-. No evidence for lepton-number violation is observed, and we have set upper limits (90% C.L.) on the branching ratio for each decay mode. The branching-ratio limits on the radiative decays and e are 0.055 and 0.064%, respectively. For the charged lepton decays ee, eee, and, the branching ratio limits are 0.040, 0.033, 0.044, and 0.049%, respectively. Upper limits on the branching ratios for the following charged lepton + neutral hadron decays are 0 (0.037%), 0 (0.044%), eK0 (0.13%), K0 (0.10%), 0 (0.21%), and 0 (0.082%). We also use these data to search for the pair production in e+e- annihilation of some unconventional particles with masses less than about 3 GeV/c2. © 1982 The American Physical Society.

Abstract

We present a measurement of the cross section for the reaction e+e- → e+e-π+π-π+π-at SPEAR. This channel is found to be large and dominated by the process γγ → ρ{variant}0ρ{variant}0 → π+π-π+π-. The cross section, which is small just above the four-pion threshold, exhibits a large enhancement near the ρ{variant}0ρ{variant}0 threshold. © 1981.

Abstract

A high-statistics study of decays into baryon final states has been done with the Mark II detector at SPEAR. A detailed test of baryon-antibaryon decay modes is presented. Substantial resonance formation is observed in multibody decays of the involving baryons. Branching ratios for a large number of decay modes are given, including the radiative decay pp. The flavor-SU(3)-forbidden decays (1385)+charge conjugate are observed with substantial branching ratios. © 1984 The American Physical Society.

Abstract

We present a measurement of the cross section for hadron production by e+e- annihilation in the vicinity of the previously observed resonance near 3.77 GeV. The data are used to determine the parameters of the (3770) resonance. The values found are: mass, 3764±5 MeV/c2, total width, 23.5±5 MeV, and partial width to electron pairs, 276±50 eV. © 1980 The American Physical Society.

Abstract

Searches for 12 neutrinoless decay modes of the which violate lepton-number conservation have been made using the reaction e+e-+-. No evidence for lepton-number violation is observed, and we have set upper limits (90% C.L.) on the branching ratio for each decay mode. The branching-ratio limits on the radiative decays and e are 0.055 and 0.064%, respectively. For the charged lepton decays ee, eee, and, the branching ratio limits are 0.040, 0.033, 0.044, and 0.049%, respectively. Upper limits on the branching ratios for the following charged lepton + neutral hadron decays are 0 (0.037%), 0 (0.044%), eK0 (0.13%), K0 (0.10%), 0 (0.21%), and 0 (0.082%). We also use these data to search for the pair production in e+e- annihilation of some unconventional particles with masses less than about 3 GeV/c2. © 1982 The American Physical Society.

Abstract

We have observed a radiative transition from the ψ to a state decaying into KSK±π∓, with mass M = 1.44-0.015+0.01 GeV/c2 and width Γ = 0.05-0.02+0.03 GeV/c2. We tentatively identify this state as the E(1420). Assuming that this state is an isospin singlet, we have determined the branching fraction product B(ψ → γE) × B(E × KKπ) = (3.6 ± 1.4) × 10-3. © 1980.

Abstract

The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 2,873 new measurements from 758 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. Particle properties and search limits are listed in Summary Tables. We 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 118 reviews are many that are new or heavily revised, including a new review on Neutrinos in Cosmology.Starting with this edition, the Review is divided into two volumes. Volume 1 includes the Summary Tables and all review articles. Volume 2 consists of the Particle Listings. Review articles that were previously part of the Listings are now included in volume 1.The complete Review (both volumes) is published online on the website of the Particle Data Group (http://pdg.lbl.gov) and in a journal. Volume 1 is available in print as the PDG Book. A Particle Physics Booklet with the Summary Tables and essential tables, figures, and equations from selected review articles is also available.The 2018 edition of the Review of Particle Physics should be cited as: M. Tanabashi (Particle Data Group), Phys. Rev. D 98, 030001 (2018).
