Abstract: I will review the OPE for Null Polygon Wilson Loops. This is an Integrability based approach for computing Wilson loop defined on polygonal contours in D dimensional gauge theories by exploring the 1 dimensional color flux tube of these theories. In one dimensions, in some theories such as N=4 SYM, we can make use of Integrability hence finding an Integrability approach -- rather than a Feynman diagrammatic one -- for studying these objects. I will discuss the status of this method -- which can be applied at both weak and strong coupling -- and present some important open questions standing in the way of a full quantum solution to this problem.
