Physical Review D (PRD), a leading journal in elementary particle physics, field theory, gravitation, and cosmology, appears monthly in two sections, D1 and D15: D1 covers experimental and theoretical particle physics as well as phenomenological aspects of quantum field theory. D15 covers gravitation, cosmology, astroparticle physics, formal aspects of the theory of particles and fields, and related areas.
In a new study, MIT physicists propose that if most of the dark matter in the universe is made up of microscopic primordial black holes—an idea first proposed in the 1970s—then these gravitational dwarfs should zoom through ...

Scientists have measured the magnetic moment of the muon to unprecedented precision, more than doubling the previous record.
Neutrinos are the "ghost particles" in the Standard Model of Particle Physics. This is because they interact weakly with ordinary matter. An interesting property of neutrinos is that they can change their identities or "flavors" ...
