High Energy Physics
High energy physics is the branch of physics that deals the nature of the particles that constitute matter and energy. High energy physics also known as Particle physics deals with the irreducibly smallest detectable particles and the fundamental interactions necessary to explain their behavior. High energy physicists works on developing a theoretical framework or models and mathematical tools to understand the current experiments in the particles. A major breakthrough in theoretical particle physics is the String theory. String theorists strive to combine the mechanics of quantum mechanics and general relativity by building a theory based on small strings.
