PHY304 - Particle Physics
This core module introduces students to the exciting field of modern particle physics. It provides the mathematical tools of relativistic kinematics, enabling them to study interactions and decays and evaluate scattering form factors. Particles are classified as fermions, the constituents of matter (quarks and leptons), or as bosons, the propagators of field. The four fundamental interactions are outlined. Three are studied in detail: Feynman diagrams are introduced to describe higher order quantum electrodynamics; weak interactions are discussed from beta decay to the high-energy electroweak unification; strong interactions, binding quarks into hadrons, are presented with the experimental evidence for a quantum number ‘colour’. The role that symmetry plays in the existing particles and their interactions, is emphasised.
