Calogero-Sutherland approach to defect blocks

Blog Article

Abstract Extended objects such EYE PRO as line or surface operators, interfaces or boundaries play an important role in conformal field theory.Here we propose a systematic approach to the relevant conformal blocks which are argued to coincide with the wave functions of an integrable multi-particle Calogero-Sutherland problem.This generalizes a recent observation in [1] and makes extensive mathematical results from the modern Vegetable Brush theory of multi-variable hypergeometric functions available for studies of conformal defects.

Applications range from several new relations with scalar four-point blocks to a Euclidean inversion formula for defect correlators.
