TLDR
The review as discussed by the authors summarizes much of particle physics and cosmology using data from previous editions, plus 3,283 new measurements from 899 Japers, including the recently discovered Higgs boson, leptons, quarks, mesons and baryons.
Abstract
The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,283 new measurements from 899 Japers, 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 heavy neutrinos, supersymmetric and technicolor particles, 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 Supersymmetry, Extra Dimensions, Particle Detectors, Probability, and Statistics. Among the 112 reviews are many that are new or heavily revised including those on: Dark Energy, Higgs Boson Physics, Electroweak Model, Neutrino Cross Section Measurements, Monte Carlo Neutrino Generators, Top Quark, Dark Matter, Dynamical Electroweak Symmetry Breaking, Accelerator Physics of Colliders, High-Energy Collider Parameters, Big Bang Nucleosynthesis, Astrophysical Constants and Cosmological Parameters.

Statistical hadronization model analysis of hadron yields in p + Nb and Ar + KCl at SIS18 energies

G. Agakishiev, +112 more
TL;DR: In this paper, the HADES data from p + Nb collisions at a center-of-mass energy of GeV were analyzed employing a statistical hadronization model, which can successfully describe the production yields of the identified hadrons,,, K 0 s, with parameters MeV and MeV, which fit well into the chemical freeze-out systematics found in heavy-ion collisions.

Exotic resonances due to η exchange

TL;DR: The meson X ( 3872 ) and several related states appear to be in large part hadronic molecules in which a heavy flavored meson (e.g., D 0 ) is bound to another heavy meson, e.g. D ¯ ⁎ 0 ). Although not only contribution to the binding, pion exchange seems to play a crucial role in generating the longest-range force between constituents as discussed by the authors.

Indirect dark matter searches in the dwarf satellite galaxy Ursa Major II with the MAGIC telescopes

Max Ludwig Ahnen, +151 more
TL;DR: In this paper, the authors used the spectral information of the recorded events for an optimal sensitivity to the explored indirect dark matter (DM) models and obtained constraints on the annihilation cross-section for different channels that are among the most robust and stringent achieved so far at the TeV mass scale.

Cosmological Moduli and the Post-Inflationary Universe: A Critical Review

TL;DR: The role of cosmological moduli in determining the post-inflationary history of the universe has been discussed in this article, where the authors discuss both the theoretical challenges and the observational implications.

First Observation of the Doubly Cabibbo-Suppressed Decay of a Charmed Baryon: Λc+→pK+π-

Seongbae Yang, +221 more
TL;DR: This is the first observation of a doubly Cabibbo-suppressed decay of a charmed baryon using a 980 fb^{-1} data sample collected by the Belle detector at the KEKB asymmetric-energy e^{+}e^{-} collider.
