  Effective Field Theories (EFTs) capture effects from heavy dynamics at low
energy and represent an essential ingredient in the context of Standard Model
(SM) precision tests. This document gathers a number of relevant scenarios for
heavy physics beyond the SM and presents explicit expressions for the Wilson
coefficients in their low-energy EFT. It includes i) weakly coupled scenarios
in which one or a few particles of different spins and quantum numbers interact
linearly with the SM and generate EFT effects at tree-level, ii) scenarios
where heavy particles interact quadratically whereupon the resulting EFT arises
only at loop-level and iii) strongly coupled scenarios where the size of Wilson
coefficients is controlled by symmetry arguments. This review aims at
motivating experimental EFT studies in which only a subset of all possible EFT
interactions is used, as well as facilitating the theoretical interpretation of
EFT fits.
