High-energy physics, also called particle physics or basic particle physics, is a branch of physics, which studies the structural properties of matters in the micro-world deeper than the atomic nucleus, and the phenomena of mutual transformation of these matters under high energy, as well as the causes and rules of these phenomena. It is a basic discipline, one of the frontiers of contemporary physics development, and cross-correlation in effective exploration of condensed matter physics and celestial particle physics. High-energy physics is a quantum exploration of particles based on "discovery and experiment", and based on the close combination of experiment and theory.

The scintillators and PMTs provided by BEIJING HAMAMATSU PHOTON TECHNIQUE INC. can be used in high-energy astrophysics (such as dark matter, neutrino, cosmic ray, high-energy celestial body, etc.) and particle collider test, and have helped major national high-energy physics research projects for many times.
