- Supersymmetric gauge theory and the Yangian

I'll explain a new connection between supersymmetric

gauge theories and the Yangian. The main result is that a twisted, deformed

version of the pure N=1 supersymmetric gauge theory is controlled by the

Yangian, in the same way that Chern-Simons theory is controlled by the quantum

group. This result is used to give an exact calculation, in perturbation

theory, of the expectation value of a certain net of n+m Wilson operators in

the deformed N=1 gauge theory. This expectation value coincides with the

partition function of a spin-chain integrable lattice model on an n-by-m

doubly-periodic lattice.
