Regge Spectral Generator and Form Factors from Hard Exclusive Amplitudes in Holographic QCD.

We show that the infinite tower of hard exclusive amplitudes in holographic light-front QCD leads to a spectral generator G(α,λ) that encodes the full Regge spectrum. The construction assumes a Poisson distribution of Fock-state components, where λ represents the average parton multiplicity above the valence configuration. The resulting generator yields a Regge spectrum invariant under continuous λ deformations. Its even- and odd-twist projections yield the meson and baryon form factors with a single value of λ, fixed by the pion charge radius, which in turn determines the full Q^{2} dependence. The constituent counting rules for both sectors follow from the structure of the spectral generator, which also provides a compact analytic representation of parton distributions.
