The passage around this formula
This is the object this article is actually about, so its bookkeeping has to be stated in full before any number is produced. is a map from pairs of “treaty configurations” — worldline, field state, coupling type, and the gap/switching pair used to build the spectrum — to the real interval [0,1] ; it carries no physical units, because it is built entirely from normalized probability densities over , whose own units of inverse time cancel between numerator and denominator of every term in the integral. It inherits, rather than assumes, the property of being a genuine metric — non-negative, symmetric, zero exactly when = almost everywhere, and satisfying the triangle…
