: These carry the fundamental forces, such as the photon for electromagnetism and the Higgs boson, which gives other particles their mass.
Particle physics is the study of the elementary building blocks of matter and radiation. At this scale, we move beyond atoms to the truly fundamental particles that have no substructure. Foundations of nuclear and particle physics
Nuclear physics focuses on the atomic nucleus—the dense core of protons and neutrons at the center of every atom. Fundamental Nuclear and Particle Physics Section : These carry the fundamental forces, such as
