Particle Physics and the Standard Model

Scope of Particle Physics

Particle physics, also called high-energy physics, investigates the fundamental particles that make up matter and radiation and the forces through which they interact. Its scope includes elementary fermions, such as quarks and leptons, and bosons, which mediate electromagnetism, the weak interaction, and the strong interaction. Quarks combine into composite particles called hadrons, including protons, neutrons, and mesons, while ordinary matter is primarily composed of first-generation quarks and leptons. The field is organized around the Standard Model, which successfully describes the strong, weak, and electromagnetic interactions and includes particles such as quarks, leptons, gauge bosons, and the Higgs boson. Particle physics also studies antiparticles, antimatter, quantum fields, particle dynamics, and possible particles beyond the Standard Model. Experimental research uses radioactive processes, cosmic rays, and particle accelerators such as the Large Hadron Collider, while theoretical research connects particle physics with quantum theory and cosmology. Open questions include the nature of gravity, dark matter, dark energy, neutrino masses, and the development of a more complete theory of nature.
