摘要: Abstract We study the form of high spin expansion minimal anomalous dimension for long operators belonging to sl ( 2 ) sector N = 4 SYM. Keeping fixed ratio j between twist and logarithm spin, expands as γ g , s f ln + 0 O 1 / . This particular double scaling limit is efficiently described, including desired accuracy in terms a linear integral equation. By its use, we are able evaluate both at weak strong coupling subleading function series j, up order 5 Thanks these results, possible extension liaison with 6 non-linear sigma model may be tackled on solid ground.
