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.

Combined analysis of charm-quark fragmentation-fraction measurements

TL;DR: A summary of measurements of the fragmentation of charm quarks into a specific hadron is given in this article, where the average has significantly reduced uncertainties compared to individual measurements, supporting the hypothesis that fragmentation is independent of the specific production process.

Neutrino quantum kinetic equations

TL;DR: In this article, the authors summarize salient features of these evolution equations and the methods employed so far to derive them and emphasize applications to situations of observational interest, emphasizing applications for situations of interest.

Including heavy spin effects in the prediction of a $\bar{b} \bar{b} u d$ tetraquark with lattice QCD potentials

TL;DR: In this article, the Born-Oppenheimer approach was extended with coupled-channel Schr\"odinger equations, allowing the heavy quark spins to be incorporated into the equation. And the existence of the tetraquark was confirmed.

Constraints on the Mass-Richness Relation from the Abundance and Weak Lensing of SDSS Clusters

TL;DR: In this paper, the scaling relation between optical richness and halo mass for a sample of SDSS redMaPPer galaxy clusters within the context of the Planck cosmological model is investigated.

On the strength of the U A (1) anomaly at the chiral phase transition in N f = 2 QCD

TL;DR: In this paper, the thermal transition of QCD with two degenerate light flavors was studied by lattice simulations using O(a)-improved Wilson quarks, and it was shown that the transition is consistent with a broad crossover.
