摘要

摘要

En 中文
We start with an n-point correlation function in a conformal gauge theory. We show that a special limit produces a polygonal Wilson loop with n sides. The limit takes the n points towards the vertices of a null polygonal Wilson loop such that successive distances x(i,i+1)(2) -> 0. This produces a fast moving particle that generates a frame for the Wilson loop. We explain in detail how the limit is approached, including some subtle effects from the propagation of a fast moving particle in the full interacting theory. We perform perturbative checks by doing explicit computations in N = 4 super-Yang-Mills theory.
