Calibrated Surfaces and Supersymmetric Wilson Loops

We study the dual gravity description of supersymmetric Wilson loops whose expectation value is unity. They are described by calibrated surfaces that end on the boundary of anti de-Sitter space and are pseudo-holomorphic with respect to an almost complex structure on an eight-dimensional slice of AdS5 × S. The regularized area of these surfaces vanishes, in agreement with field theory non-renormalization theorems for the corresponding operators. ∗[email protected], [email protected], [email protected], [email protected]
