We study special quantum field theories with additional spacetime symmetries, namely conformal symmetry and extended supersymmetry. After inserting an extended probe, represented by a Wilson loop, we study the residual symmetry pattern and we compute correlation functions of local operators in presence of the Wilson loop. We exploit special tools of superconformal theories, such as supersymmetric localization and conformal defect analysis. and we obtain exact results for special classes of observables.
