Particle and Nuclear Physics
Particle physics research is mostly concentrated on subatomic particles which include atomic constituents such as electrons, protons and neutrons produced by radioactive and scattering processes such as photons, neutrinos, and muons as well as a wide range of unusual particles. Dynamics of particles is also governed by quantum mechanics and they exhibit wave–particle duality, which display the particle-like behavior under the definite experimental conditions. Nuclear physics research is concentrated mostly on understanding the matter which is composed of quarks and gluons which usually makes up 99% of the mass in the universe. The field of particle physics developed out of nuclear physics and is naturally taught in close association with nuclear physics.
Particle physics is the division of physics which studies the nature of the particles that constitute matter and radiation. The word "particle" can refer to several types of very small objects such as protons, gas particles, or household dust and the particle physics which commonly investigates the irreducibly fundamental force fields and also the irreducibly smallest detectable particles required to explain them. Nuclear physics is also the field of physics that studies about the atomic nuclei and their relations and their constituents. The most commonly identified application of nuclear physics is nuclear power generation and the research has led to various applications in various fields which includes nuclear medicine and nuclear weapons, ion embedding, magnetic resonance imaging in materials engineering and radiocarbon dating in archaeology and geology.
