 Description We study the spectrum of local operators living on a defect in a generic conformal field theory, and their coupling to the local bulk operators. We establish the existence of universal accumulation points in the spectrum at large $s$, $s$ being the charge of the operators under rotations in the space transverse to the defect. Our tools include a formula that inverts the bulk to defect OPE and is analytic in $s$, analogous to the Caron-Huot formula for the four-point function. Some important assumptions are made in deriving this result: we comment on them.  Material:
