Wilson Loop

A Wilson Loop is a concept in physics, specifically in quantum field theory, that helps describe how particles like quarks interact through force fields such as the strong force. Imagine tracing a closed path or loop in space—and then measuring how the force fields influence any particles or charges along that loop. The result provides insight into whether the force acts like a string, pulling particles together, which is important for understanding phenomena like confinement in quantum chromodynamics (QCD). Essentially, Wilson Loops are mathematical tools used to study the properties of forces that bind fundamental particles.
