Vector Meson Dominance and Vector Meson Production
Abstract
Against a background supported by the three pillars of emergent mass, this contribution challenges the fidelity of vector meson dominance as an instrument for relating the electromagnetic vector-meson (V) production reaction e + p → e′ + V + p to the hadronic process V + p → V + p. It also describes a viable reaction model for exclusive photoproduction of light and heavy vector mesons from the proton, which exposes the qq̅ content of the photon. That model's successes reveal that it is premature to link extant V + p → V + p data with, for instance, in-proton gluon distributions, the QCD trace anomaly, or pentaquark production. Improved reaction theory and more precise data are required before the validity of such links can objectively be assessed.
