On the Wilson-Fisher Fixed Point in the Limit of Integer Spacetime Dimensions

IHES

The Wilson–Fisher (WF) fixed point, a scalar field theory with a quartic interaction in $d = 4 - \epsilon$ dimensions, is the textbook example of a weakly coupled CFT. The epsilon expansion accurately reproduces the critical exponents of the $d = 3$ and the $d = 2$ Ising model. This has led to the common view that WF defines a continuous family of CFTs in non-integer dimensions, interpolating betw
