Title: Correlators of BPS lines in conformal field theory
Abstract: We study the properties of correlation functions of conformal line operators in four-dimensional superconformal field theories. These are treated as n-point functions on the configuration space of conformal line operators. An especially simple set of these correlators are those of BPS line operators which are annihilated by an appropriate subset of the supercharges. Perhaps surprisingly, their topological properties are sensitive to the signature of the space-time metric and to the signature the line operators.
