Query: A search for non-qqbar mesons in the WA102 experiment at the CERN Omega
  Spectrometer   A study of central meson production as a function of the difference in
transverse momentum dPT of the exchanged particles shows that undisputed qqbar
mesons are suppressed at small dPT whereas the glueball candidates are
enhanced.
