Physical Review D, a leading journal in elementary particle physics, field theory, gravitation, and cosmology, appears monthly in two sections, D1 and D15:

D1: reports on experimental high-energy physics, phenomenologically oriented theory of particles and fields, cosmic-ray physics, electroweak interactions, applications of QCD and lattice gauge theory.

D15: covers general relativity, quantum theory of gravitation, cosmology, particle astrophysics, formal aspects of theory of particles and fields, general and formal development in gauge field theories and string theory. (source)
