Large N Quantum Chromodynamics

Large N Quantum Chromodynamics (QCD) is a theoretical approach where the number of color charges, N, in the strong nuclear force is considered very large. In standard QCD, N=3, representing three types of color particles. By extending N to large values, physicists find simplifications that reveal patterns and behaviors of quarks and gluons, the particles that make up protons and neutrons. This helps in understanding complex phenomena like confinement and hadron formation, as certain calculations become more manageable. While not directly describing reality, large N QCD provides valuable insights into the strong interaction that binds nuclear matter together.
