"Planar N=4 Gauge Theory, the Hubbard Model, and Transcendentality"

Presented by Matthias Staudacher, Max-Planck-Institut fuer Gravitationsphysik (AEI)

Wednesday, February 22, 2006, 1:30 pm — Small Seminar Room, Bldg. 510

We review recent indications for the all-loop integrability of planar N=4 gauge theory, and compare to similar, parallel developments in the dual AdS string theory description. We discuss a very recent, first candidate for the gauge theory's non-perturbative dilatation operator in a sector of the theory: The Hubbard model. Finally we apply the integrability conjecture to the sector of twist operators, and find a novel all-loop scaling function for their large spin anomalous dimension.
