Effective field theory (EFT) is a systematic framework based on a separation of scales, with matching and the renormalization as essential computational tools. The inclusion of higher-dimensional operators and increasing demands for higher perturbative orders have driven significant automation of EFT calculations. Conformal field theories (CFTs), by contrast, are scale-invariant and characterized by the spectrum of operators and their operator product expansion (OPE) coefficients. While these data are known to high precision in simple cases from non-perturbative methods, they remain difficult to compute in more general settings. I will present our ongoing effort to perturbatively compute the operator spectrum and OPE coefficients using the aforementioned EFT techniques.
