Two point functions in defect CFTs

A bstract This paper is designed to be a practical tool for constructing and investigating two-point correlation functions in defect conformal field theory, directly physical space, between any two bulk primaries or primary primary, with arbitrary spin. Although geometrically elegant ultimately more powerful approach, the embedding space formalism gets rather cumbersome when dealing mixed symmetry tensors, especially projection space. The results this provide an alternative method studying generic d -dimensional theory flat p ? = q co-dimensions. We tabulate some examples of involving conserved current, energy momentum tensor Maxwell strength, while analysing constraints arising from conservation equations motion. obtaining bulk-to-defect correlators also explained. Some explicit are considered: free scalar on ? × (? /? 2 ) four dimensional wedge.
