Cusp anomalous dimension in N=4 SYM at strong coupling
Seminar Room 1, Newton Institute
We construct an exact analytical solution to the integral equation which is believed to describe logarithmic growth of the anomalous dimensions of high spin operators in planar N=4 super~Yang-Mills theory and use it to determine the strong coupling expansion of the cusp anomalous dimension. (Based on the work arXiv:0708.3933[hep-th] done in collaboration with Gregory Korchemsky and Jan Kotanski).
If it doesn't, something may have gone wrong with our embedded player.
We'll get it fixed as soon as possible.
