The authors compute the Casimir energy of two parallel static wires at zero temperature in pure $(2+1)$- dimensional Yang-Mills theory. They show that the result is in good agreement with recent lattice simulations.

A calculation determines four distinct contributions to the proton mass, more than 90% of which arises entirely from the dynamics of quarks and gluons.

Motivated by results from the EDGES experiment, the authors investigate a novel mechanism for heating up the intergalactic medium, just prior to the first star formation. This mechanism contributes to the spin temperature of the 21-cm hyperfine line of atomic hydrogen.

The 60th anniversary edition of the Review of Particle Physics, published in Physical Review D, provides a comprehensive review of the field of particle physics and of related areas in cosmology. Topics include Higgs bosons, supersymmetry, big bang nucleosynthesis, probability, statistics, and accelerators and detectors.
