Surprises in the ordinary: O(N) invariant surface defect in the ϵ-expansion

Abstract We study an O(N) invariant surface defect in the Wilson-Fisher conformal field theory (CFT) in d = 4 – ϵ dimensions. This defect is defined by mass deformation on a two-dimensional surface that generates localized disorder and is conjectured to factorize into a pair of ordinary boundary con...
