Down-up EFT approach
In the Down-up approach we interpret an available field theory (e.g. the SM) as a low energy EFT of some unknown full high energy theory. We add new operator terms $c_n\frac{\mathcal{O}n}{\Lambda^n\text{NP}}$ to the low energy theory and can try to estimate the scale of NP with current data.
E.g. scale of NP from Effective theory of weak Interaction can be estimated from $G_F$ to $M_W \approx 80$GeV.
