Project Title: How Hadrons keep their Quarks

The strong force is one of the four fundamental forces of nature; it binds protons and neutrons to form atomic nuclei, and is responsible for 98% of a person¿s mass. Protons and neutrons are just the most common members of a family of strongly interacting particles: the hadrons. This large family can be understood in terms of a small number of constituent particles called quarks, which are bound together in twos or threes. How does the strong force bind quarks, and why are they never alone? The restriction of quarks to bound-states is called confinement, and it is the central mystery of the strong force. According to the theory of Quantum Chromodynamics (QCD), quarks interact by exchanging another particle, called a gluon. This theory is mathematically elegant, but the equations are difficult to solve. How - and, indeed, if - Quantum Chromodynamics produces confinement.
