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.
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 …
