“…The production of mesons in the central region of proton-proton collisions (pp → ppM) via a gluonic Pomeron has traditionally been regarded as a potential source of glueballs [1]. However, well-established quark-antiquark (qq) mesons are also known to be produced and this has led to searches for a selection mechanism that could help to distinguish among such states.…”

We demonstrate that the azimuthal dependence of central meson production in hadronic collisions, when suitably binned, provides unambiguous tests of whether the Pomeron couples like a conserved vector-current to protons. We discuss the possibility of discriminating between qq and glueball production in such processes. Our predictions apply also to meson production in tagged two-photon events at electron-positron colliders and to vector-meson production in ep collisions at HERA.

“…In the case of deep inelastic scattering, the momentum fraction of the proton x is precisely the Bjorken variable x Bj . The unpolarized DIS cross section can also be written in the classic form, with hadronic tensors [9]: 22) with the structure functions F 1 (x) and F 2 (x), given in the Q 2 → ∞ limit by 23) which encapsulate the soft processes.…”

“…There are other models like the "glue-lego" model [2], the flux-tube model [3] and the non-relativistic potential model [4] which are, at least in their original forms, more or less excluded by the available lattice data. A relativistic version of the potential model is given by a recent Bethe-Salpeter calculation with massive constituent gluons [5].…”

Using simple and general arguments we propose an effective Hamiltonian for the description of low-energy pure QCD. The Hamiltonian is a function of spatially constant collective modes. Its eigenstates can be organized into bands classified by the irreducible representations of an O(8) group. The latter also determine parity and charge conjugation of the states. The energy spectrum agrees well with the glueball spectrum as measured on the lattice, and in particular the level ordering with respect to spin is naturally explained.
