abstract = {Effective Field Theory calculations used in countless phenomenological analyses
employ dimensional regularization, and at intermediate stages of computations, the operator
bases extend beyond the four-dimensional ones. The extra pieces — the evanescent operators
— can ultimately be removed with a suitable renormalization scheme, resulting in a finite
shift of the physical operators. Modern Effective Field Theory matching techniques relying
on the method of expansion by regions have to be extended to account for this. After
illustrating the importance of these shifts in two specific examples, we compute the finite
shifts required to remove all evanescent operators appearing in the one-loop matching of
generic ultraviolet theories to the Standard Model Effective Field Theory and elucidate the
formalism for generic Effective Field Theory calculations.},
