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.
In the world of particle physics, where scientists unravel the mysteries of the universe, artificial intelligence (AI) and machine learning (ML) are making waves with how they're increasing understanding of the most fundamental ...
