Symbol kappa
What this part means
surface gravity with inverse-time units in the chosen normalization.
Its job in the formula
kappa 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
so the adapter into the exponential ledger is . 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. 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 . They translate a verified overlap into operational thresholds.
