Resonance production in central pp collisions at the CERN Omega Spectrometer

A study of resonance production in central pp collisions is presented as a function of several kinematical variables. In particular the difference in the transverse momentum (dPT) of the exchanged particles shows that undisputed qq̄ mesons are suppressed at small dPT whereas glueball candidates are enhanced and in addition, the azimuthal angle φ gives information on the nature of the Pomeron.
