3171 — Finite Masses Preserve the Cascade Rank Until Threshold
Result
On the positive-real narrow-width protected slice, the finite-mass rate and signed angular kernels have Jacobian determinant
It is nonzero throughout the open parent threshold domain. At the exact threshold , the Källén factor vanishes and the signed port collapses.
Limit
Complex phase, finite widths, off-shell transport, reconstruction of , and detector calibration remain open. The response conditionally identifies magnitudes and selects no values.
