Maths HEP Lunchtime Seminars: A new family of supersymmetric Wilson loops and their string theory duals
25 April 2008 13:00 in CM221
In this talk I will present a new family of supersymmetric Wilson loop operators in N=4 supersymmetric Yang-Mills theory. These operators are naturally defined on a 3-sphere in space-time and generically preserve two supercharges of the N=4 superconformal algebra. I will then discuss these operators in string theory and show that the dual string solutions satisfy a first order differential equation. This equation expresses the fact that the strings are "pseudo-holomorphic" surfaces with respect to a novel almost complex structure.
