Superconformal Boundaries in 4-epsilon Dimensions
Motivated by possible applications to critical systems with emergent supersymmetry, we study SCFTs with supersymmetry preserving boundary conditions. Our formalism is based on the conformal bootstrap and can be applied to theories with four supercharges in any, in principle continuous, number of dimensions. As an application, we calculate the two-point function of chiral operators at one loop in the epsilon expansion, and extract an infinite amount of new CFT data. We also perform an explicit Feynman diagram calculation and find perfect agreement with the bootstrap results.
