Abstract:
The half-supersymmetric Wilson loop in N= 4
SYM is arguably the central non-local
operatorin the AdS/CFT correspondence. On
the field theory side, the vacuum expectation
values of Wilson loops in arbitrary
representations of SU(N) are captured to all
orders in perturbation theory by a Gaussian
matrix model. Of prominent interest are the k-
symmetric and k-antisymmetric
representations, whose gravitational
description is given in termsof D3- and D5-
branes, respectively, with fluxes in their world
volumes. At leading order in N and λ the
agreement in both cases is exact. In this talk
we explore the structure of the next-to-leading
order correction in the matrix model and
compare with existing string theory
calculations. We also discuss ways to
improve the holographic computations to
match the sub-leading corrections in the
matrix model.
