What is meant with the fact that Super Yang-Mills flows to a conformal field theory in the infrared? Also, is this a general fact or does this depend on the fact of considering a certain class of theories (such as $N=4$, $d=3$ for example)?
I have seen this statement numerous times in various articles such as
Every time this fact is stated by some author it is given as a known thing, and it is not explained. With an online research I could not make sense of this.
Could someone please explain?
