Filtering glueball from qq̄ production in proton proton or double tagged e+e−→e+e−R and implications for the spin structure of the

The production of JPC=1++,0−+ and 2−+ mesons in double tagged e+e−→e+e−R is calculated and found to have the same polarisation and dynamical characteristics as observed in pp→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.
