The -expansion of the codimension two twist defect from conformal field theory

arXiv:1607.05551 · doi:10.1093/ptep/ptw115

Abstract

We apply the framework of Rychkov-Tan arXiv:1505.00963 to the codimension two twist defect at the Wilson-Fisher fixed point in dimensions. We obtain the scaling dimensions of the operators on the defect up to the lowest nontrivial order in the -expansion without using Feynman diagram computation. Our results agree with the known results.
