Radial coordinates for defect CFTs

Radial coordinates for defect CFTs

Abstract We study the two-point function of local operators in the presence of a defect in a generic conformal field theory. We define two pairs of cross ratios, which are convenient in the analysis of the OPE in the bulk and defect channel respectively. The new coordinates have a simple geometric i...
