Infinite chiral symmetry in four dimensions
Balt van Rees
(CERN)
Abstract:
We describe a new correspondence between four-dimensional conformal field theories with extended supersymmetry and two-dimensional chiral algebras. The meromorphic correlators of the chiral algebra compute correlators in a protected sector of the four-dimensional theory. Infinite chiral symmetry has far-reaching consequences for the spectral data, correlation functions, and central charges of any four-dimensional theory with N=2 superconformal symmetry.

Holographic accelerating heavy quark
Gordon Semenoff
(British Columbia U.)
Abstract:
A formula for the interaction energy of an eternally accelerated heavy quark-antiquark pair in N=4 Yang-Mills theory is derived and its implications are discussed, both in the context of strongly coupled Yang-Mills theory and in its dual, the IIB string theory.
