Regge spectral generator and form factors from hard exclusive amplitudes in holographic QCD

Abstract

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