Which of the following terms are equivalent? and in what cases/limits do the non-equivalent terms become equivalent?
A) a scale invariant quantum field theory.
B) a conformal quantum field theory.
C) a quantum field theory whose bare coupling constants are all dimensionless.
D) a quantum field theory whose physical coupling constants are all dimensionless.
E) a quantum field theory with everywhere-vanishing beta functions.
F) a quantum field theory in a fixed point of the renormalization group flow.
Thanks.
