About
In EFT, the computation of anomalous dimensions of composite operators in $4-\epsilon$ dimensions is central. Precisely this computation has a completely different application, namely to the $\epsilon$-expansion of conformal field theories (CFTs), where instead of taking $\epsilon\to0$ one is interested in results for 3d theories at $\epsilon=1$. Anomalous dimensions of composite operators correspond to directly observable quantities in these 3d CFTs, and multiloop results can be compared with non-perturbative methods such as MC simulations and the conformal bootstrap. I will explain this new synergy between techniques developed for EFT and applications to CFT, focussing on the use of multiloop anomalous dimensions within the conformal bootstrap.
