What this part means
The lower label selects a particular version, component, or indexed member of the quantity. For example, x₀ and xₜ can be values at different positions.
Its job in the formula
A subscript distinguishes a version, component, step, or member of a quantity. It does not automatically mean multiplication.

The passage around this formula
No experiment has isolated an Unruh-like signal from this system, and this article does not claim otherwise. Measured storage-ring polarizations match the standard Sokolov-Ternov prediction, once ordinary QED corrections are included, at the percent level, and circular motion is not uniform linear acceleration — a fact Bell and Leinaas themselves stressed, since the field seen by a circulating charge is not simply a Rindler wedge, and the comparison to 's idealized eternal-linear-acceleration spectrum is only approximate even before synchrotron backgrounds are considered. What the storage-ring case does supply, honestly, is a parameter range: it is the one setting where the…

A subscript is a label attached below a symbol. It often selects a time step, component, category, or member of a sequence.
