We study correlation functions of single trace operators approaching the cusps of null polygons in a double-scaling limit. We find that these correlators can be uniquely fixed through a set of coupled lattice PDEs of Toda type. These results are applicable to most conformal gauge theories.
We consider correlation functions of single trace operators approaching the cusps of null polygons in a double-scaling limit where so-called cusp times t(i)(2) = g(2) log x(i-1,i)(2) logx(i,i+1)(2) are held fixed and the 't Hooft coupling is small. With the help of stampedes, symbols, and educated guesses, we find that any such correlator can be uniquely fixed through a set of coupled lattice PDEs of Toda type with several intriguing novel features. These results hold for most conformal gauge theories with a large number of colors, including planar N = 4 SYM.
