Question

Quantum field theory being deformation of conformal field theory?

Answer 1

The idea might be that by rescaling a QFT you reach a renormalization group fixed point; that fixed point is scale-invariant and therefore in many cases conformally invariant; then can we recover the original QFT by deforming that CFT? This is how I would understand the question, but I do not know the answer. Anyway it is no more absurd to consider QFT as a deformation of CFT, than to consider QFT as a deformation of free QFT.
