Gluon scattering amplitudes as flux-tube partition functions

Regular Seminar Benjamin Basso (ENS Paris)

14:00 QMW
room G.O. Jones 610

In this talk I will explain how to compute gluon scattering amplitudes at finite coupling in planar N=4 SYM theory, using the duality with null polygonal Wilson loops, conformal symmetry, and the integrability of the colour flux tube dynamics. After introducing the main ideas and results, I will present some applications of this formalism at strong coupling and discuss the validity of the semiclassical (dual) string description.
