What the article says around this equation
, viewed as a function of for fixed everything else, has a natural reading as a spectrum: it says how much excitation probability accumulates at each possible gap, for a whole notional bank of detectors sharing one trajectory, one switching profile, and one field state, differing only in . Restricting to the excitation branch >0 — “did this detector behave as though it absorbed a quantum” is the only branch this article treats as bearing on particle content, since the decay branch <0 mixes genuine field structure with detector-specific spontaneous-emission physics that is present even in flat, empty spacetime with no field excitation at all —…
