Dynamics of glueball and qq production in the central region of pp collisions

A strong dependence of meson production with different J/sup PC/ on the angle between the transverse momentum vectors of the outgoing protons is observed. The phi and t dependences of several resonances with J/sup PC/=0/sup +or-+/, 1/sup ++/, 2/sup +or-+/ can be described by a model of double Pomeron exchange for the soft Pomerons acting as nonconserved vector currents. The 0/sup ++/ and 2/sup ++/ sector reveals a systematic behavior in the data that appears to distinguish between qq and nonqq or glueball candidates. (6 refs).
