Basic concepts of high energy physics
High energy physics, also known as particle physics or elementary particle physics, is a branch of physics that studies the structural properties of matter in the microscopic world deeper than the atomic nucleus, and under high energy, these The phenomenon of mutual transformation of substances, as well as the causes and laws of these phenomena. It is a basic subject and one of the frontiers of the development of contemporary physics, and it is an effective exploration of condensed matter physics and celestial particle physics.
