摘要
We determine central charges, critical exponents and appropriate gradient flow relations for non-supersymmetric vector-like and chiral Gauge-Yukawa theories that are fundamental according to Wilson and that feature calculable UV or IR interacting fixed points. We further uncover relations and identities among the various local and global conformal data. This information is used to provide the first extensive characterization of general classes of free and safe quantum field theories of either chiral or vector-like nature via their conformal data. Using large N-f techniques we also provide examples in which the safe fixed point is nonperturbative but for which conformal perturbation theory can be used to determine the global variation of the a central charge.
