Abstract: Conformal field theories are defined by the CFT data: the spectrum of primary operator dimensions and OPE coefficients. Over the last decade, our knowledge of CFT data has accelerated at many frontiers. This has been facilitated by the rapid development of various numerical and analytic CFT techniques for charting the spectra of CFTs perturbatively and non-perturbatively. In this talk, I will first put these results into a holistic context. Then I will present new results at the perturbative, diagrammatic, frontier, where we use techniques developed for effective field theories for overcoming the technical challenges involving operator bases and diagram evaluation at multi-loop level.
