| contents | We show that the infinite tower of hard exclusive amplitudes in holographic light-front QCD leads to a spectral generator $G(α,λ)$ which encodes the full Regge spectrum. The construction assumes a Poisson distribution of Fock-state components, where $λ$ represents the average parton multiplicity above the minimal valence configuration. The resulting generator yields a Regge spectrum invariant under continuous $λ$-deformations and provides an analytic representation of physical form factors. The coherent summation also yields a compact analytic representation of parton distributions. |
