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.
Scientists can use powerful colliders to smash atomic nuclei together to create a quark-gluon plasma (QGP). This "soup" of quarks and gluons, some of the fundamental building blocks of matter, filled the early universe. Tracking ...

Understanding the behavior of nuclear matter—including the quarks and gluons that make up the protons and neutrons of atomic nuclei—is extremely complicated. This is particularly true in our world, which is three dimensional. ...

Inside the proton are elementary particles called quarks. Quarks and protons have an intrinsic angular momentum called spin. Spin can point in different directions. When it is perpendicular to the proton's momentum, it is ...
