User:SPat/High energy physics
High energy physics is a branch of physics dealing with study of matter and interactions at the smallest scales.[1] The smaller the length scale of interest, the higher is the required energy of the probe used for observation.[2] Research in high energy physics comprises primarily of problems in particle physics and nuclear physics, but also includes the study of cosmic rays and other closely related areas of astrophysics.[citation needed]
The study of high energy phenomena began in the first half of the twentieth century, primarily with cosmic ray physics.[3] With the construction of increasingly more powerful particle accelerators, the field has grown rapidly starting in the 1950s[2]
