The passage around this formula

Here Oi\mathcal{O}_i are Standard-Model-field operators of dimension six, cic_i are unknown coefficients, and Λ\Lambda is the mass scale of whatever new physics has been integrated out. This is the Standard Model Effective Field Theory (SMEFT) framework used across current LHC and dark-matter searches. Its…
