Particle physics is a research area focused on the fundamental constituents of matter and radiation and the interactions governing them, typically described by quantum field theories such as the Standard Model. It investigates quarks, leptons, gauge bosons, and the Higgs boson, and their dynamics under the strong, weak, and electromagnetic forces, often at high energies where new degrees of freedom become accessible. The field relies on large-scale experiments (e.g., collider-based and fixed-target facilities), precision measurements, and advanced detectors, while also exploring physics beyond the Standard Model, including neutrino properties, dark matter candidates, and potential new symmetries or interaction sectors.
Neutrinos are elementary particles that are predicted to be massless by the standard model of particle physics, yet their observed oscillations suggest that they do in fact have a mass, which is very low. A further characteristic ...
In physics, there are two great pillars of thought that don't quite fit together. The Standard Model of particle physics describes all known fundamental particles and three forces: electromagnetism, the strong nuclear force, ...
