Abstract
We consider Wilson loops in planar mathcalN = 4 SYM for null polygons in the limit of two crossing edges The analysis is based on a renormalisation group technique We show that the previously obtained result for the leading and nextleading divergent term of the two loop hexagon remainder is in full agreement with the appropriate continuation of the exact analytic formula for this quantity Furthermore we discuss the coefficients of the leading and nextleading singularity for the three loop remainder function for null ngons with n ≥ 6
