Γ=Cκ2.\Gamma=\frac{C\kappa}{2}.
CC

What this part means

their dimensionless decohering flux.

Its job in the formula

C 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, κ\kappa is surface gravity with inverse-time units in the chosen normalization, and T is the associated Killing time.

The passage around this formula

so the adapter into the exponential ledger is Γ=Cκ2\Gamma=\frac{C\kappa}{2}. Here C is their dimensionless decohering flux, κ\kappa is surface gravity with inverse-time units in the chosen normalization, and T is the associated Killing time. Their calculation fixes the numerical factor absent from earlier scaling estimates and evaluates C for an observer on the symmetry axis of a Kerr black hole [ 3 ] . The information equations above neither alter C nor derive κ\kappa . They translate a verified overlap into operational thresholds.
