The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,324 new measurements from 878 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 120 reviews are many that are new or heavily revised, including a new review on High Energy Soft QCD and Diffraction and one on the Determination of CKM Angles from B Hadrons. The Review is divided into two volumes. Volume 1 includes the Summary Tables and 98 review articles. Volume 2 consists of the Particle Listings and contains also 22 reviews that address specific aspects of the data presented in the Listings. The complete Review (both volumes) is published online on the website of the Particle Data Group (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 available in print and as a web version optimized for use on phones as well as an Android app.

A model of a three Pomeron contribution to high energy elastic pp andpp scattering is proposed. The data are well described for all momenta (0.01 ≤ |t| ≤ 14. GeV 2 ) and energies (8.The model predicts the appearance of two dips in the differential cross-section which will be measured at LHC. The parameters of the Pomeron trajectories are: α(0) P1 = 1.058, α ′ (0) P1 = 0.560 (GeV −2 ); α(0) P2 = 1.167, α ′ (0) P2 = 0.273 (GeV −2 ); α(0) P3 = 1.203, α ′ (0) P3 = 0.094 (GeV −2 ).

The inelastic scattering of the brane fields induced by t-channel gravireggeons exchanges in the RS model with a small curvature κ is considered, and the imaginary part of the eikonal is analytically calculated. It is demonstrated that the results can be obtained from the corresponding formulae previously derived in the ADD model with one extra dimension of the size R c by formal replacement R c → (πκ) −1 . The inelastic cross section for the scattering of ultra-high neutrino off the nucleon is numerically estimated for the case κ ≪M 5 ∼ 1 TeV, whereM 5 is a reduced Planck scale in five warped dimensions.

We discuss a recently proposed interpretation of some model descriptions of the proton-proton elastic scattering data as a manifestation of alleged relative transparency of the central part of the interaction region in the impact parameter space. We argue that the presence of nonzero real part of the elastic scattering amplitude in the unitarity condition enables to conserve the traditional interpretation.
