In the first part of the talk, I will introduce the notions of evanescent operators, evanescent schemes, and prescriptions in the context of higher-order EFT computations using dimensional regularization. These operators play a crucial role in both matching and RGE running computations, and their treatment is often cumbersome and challenging. In the second part of the talk, I will present recent work aimed at simplifying the treatment of evanescent contributions in EFT. More precisely, I will show how their contributions can be interpreted as loop corrections to four-dimensional Dirac identities (shifts), and how this perspective significantly simplifies their treatment, particularly when changing operator bases or evanescent schemes.
