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-ε dimensions. We obtain the scaling dimensions of the operators on the defect up to the lowest nontrivial order in the ε-expansion without using Feynman diagram computation. Our results agree with the known results.
