Title | Multi-point multi-loop Null Polygons from Fishnet theory to N=4 SYM |
Abstract | ``Null polygons" in N=4 SYM theory capture the UV behaviour of a planar multi- point correlator of local operators inserted at the vertices of a light-like polygon. The leading UV divergences of null polygons satisfy a hierarchy of coupled Toda field theory equations according to a recent conjecture [E.O., Vieira 22]. I will present some progress towards the prediction of Null Polygons beyond leading logarithm via the hexagons technique, appropriately truncated in the light-cone regime. The method, still conjectural, relies on a series of weak- coupling derivations performed in the Fishnet limit of the theory, where the hexagon representation is achieved in the basis of the excitations of a conformal Heisenberg magnet in the principal series. I will present a series of worked-out examples of this method for 6-point correlators at a few loop orders. |
