The $ε$-expansion of the codimension two twist defect from conformal field theory
Published 19 Jul 2016 in hep-th | (1607.05551v3)
Abstract: We apply the framework of Rychkov-Tan arXiv:1505.00963 to the codimension two twist defect at the Wilson-Fisher fixed point in $4-\epsilon$ dimensions. We obtain the scaling dimensions of the operators on the defect up to the lowest nontrivial order in the $\epsilon$-expansion without using Feynman diagram computation. Our results agree with the known results.
