What this part means
A raised number can be a power. When it is a label or bound, it selects a case or the upper limit of a sum; the formula’s structure distinguishes these uses.
Its job in the formula
A raised mark can be a power or an index. Its position and the surrounding notation determine which.

The passage around this formula
Here are Standard-Model-field operators of dimension six, are unknown coefficients, and 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 value is precise and limited: it lets an experiment quote a model-independent bound on / from a measured deviation (or non-deviation) without committing to what specific particle generates that coefficient, and separate models mapping onto the same operators can then be constrained together rather than one at a time. It cannot, by itself, tell you the new particle’s mass or spin; it…

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.
