Evidence that the Pomeron transforms as a non-conserved vector current

TL;DR

This paper presents evidence that the soft Pomeron behaves as a non-conserved vector current, supported by azimuthal angle and quantum number dependences, enabling future quantitative modeling of meson and glueball production.

Contribution

It provides experimental evidence supporting the Pomeron as a non-conserved vector current, a novel interpretation in high-energy diffraction.

Findings

Dependences on azimuthal angle, t, and meson J^P are consistent with the vector current hypothesis.

Supports the potential for quantitative descriptions of meson and glueball production.

Proposes further tests to validate the non-conserved vector current nature of the Pomeron.

Abstract

The detailed dependences of central meson production on the azimuthal angle phi, t and the meson J^P are shown to be consistent with the hypothesis that the soft Pomeron transforms as a non-conserved vector current. Further tests are proposed. This opens the way for a quantitative description of q-qbar and glueball production in p p -> p M p.
