Filtering glueball from $q\bar{q}$ production in proton proton or double tagged $e^+e^- \to e^+e^-R$ and implications for the spin structure of the Pomeron

The production of $J^{PC} = 1^{++},0^{-+}$ and $2^{-+}$ mesons in double tagged same polarisation and dynamical characteristics as observed in $pp \to ppR$. Implications for the spin structure of the Pomeron are considered. Production of $0^{++},2^{++}$ mesons in these two processes may enable the dynamical nature of these mesons to be determined.
