Scaling dimensions in QED3 from the ϵ-expansion
Scaling dimensions in QED3 from the ϵ-expansion
We study the fixed point that controls the IR dynamics of QED in d = 4 − 2ϵ dimensions. We derive the scaling dimensions of four-fermion and bilinear operators beyond leading order in the ϵ-expansion. For the four-fermion operators, this requires the computation of a two-loop mixing that was not …
