Equation 27 · Part 2 · How Fast Can a Horizon Learn Which Path You Took?
Symbol T
What this part means
the associated Killing time.
Its job in the formula
T occurs above the fraction bar. The numerator is divided by the entire denominator below it.

Where the article explains it
Here C is their dimensionless decohering flux, is surface gravity with inverse-time units in the chosen normalization, and T is the associated Killing time.
The passage around this formula
Gralla and Wei calculate the large-holding-time overlap for nonextremal bifurcate Killing horizons in electromagnetic and Klein–Gordon analogues. In their natural-unit convention, . so the adapter into the exponential ledger is
Learn the underlying idea
A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
