Particles and Fields Physics (PFP)

Section Information

Particles and Fields Physics focuses on the study of fundamental particles, their interactions, and the underlying fields that govern physical processes at the smallest scales. It investigates the principles of quantum field theory, particle dynamics, symmetries, and interactions that form the foundation of modern high-energy physics and cosmology.

Modern research in this field includes the Standard Model, beyond-the-Standard-Model physics, quantum chromodynamics, electroweak theory, neutrino physics, dark matter and dark energy studies, collider physics, and early-universe cosmology. Advances in theoretical frameworks, detector technologies, numerical simulations, and experimental discoveries continue to shape our understanding of particle behavior and the structure of the universe.

This section publishes theoretical analyses, experimental studies, simulations,模型 development, reviews, and case reports addressing particle interactions, field theory, symmetries, fundamental forces, experimental measurements, and emerging questions in high-energy and astroparticle physics.
