Particle production is a fundamental process in physics involving the creation of new elementary or composite particles from energy or the transformation of existing particles, typically occurring during high-energy interactions or extreme conditions. As a research field, it investigates the mechanisms, rates, and properties of these newly produced particles, which are governed by fundamental forces and energy-mass conversion (E=mc²). Its significance lies in providing insights into fundamental interactions, the structure of matter, and the dynamics of high-energy phenomena observed in particle collisions, astrophysical processes, and the early universe.
