The Epsilon-Expansion from Conformal Field Theory
Published 5 May 2015 in hep-th and cond-mat.stat-mech | (1505.00963v3)
Abstract: Conformal multiplets of $\phi$ and $\phi3$ recombine at the Wilson-Fisher fixed point, as a consequence of the equations of motion. Using this fact and other constraints from conformal symmetry, we reproduce the lowest nontrivial order results for the anomalous dimensions of operators, without any input from perturbation theory.
