The passage around this formula
where each is a dimension-six operator built from Standard Model fields and is a dimensionless Wilson coefficient set by the details of the underlying theory. This notation is worth showing because it makes the comparison’s real structure explicit: SUSY, extra dimensions, and dark-sector models are each, in this language, a specific choice of which operators get generated and with what coefficients. A null search in a global SMEFT fit constrains / combinations directly from precision electroweak, Higgs, and flavor data, without committing to which particle content produced them [ 7 ] . The tradeoff is exactly the one implied by that…

An exponent tells how a base is used in multiplication. In x³, x is the base and 3 is the exponent: x³ = x × x × x.
