Abstract
After a brief review of the theoretical and phenomenological motivation for the existence of gluonic resonances, we examine the expected properties of such states, and consider possible tests for their presence in the hadronic spectrum below 1.5 GeV in mass. The scalar mesons can be classified as an approximately ideally mixed nonet with an additional isoscalar, the S ∗, with all the expected properties of a scalar glueball. It is suggested that the η′ contains a large proportion of glue as well as strange quarks and that, if the E(1420) is not a pseudoscalar, two further pseudoscalars await discovery in the low-lying meson spectrum. The pomeron, a narrow resonance in the ππ D-wave, must be found with a mass around or slightly below that of the S ∗. If the pomeron has a daughter vector glueball which, as has been argued, is fairly close to the φ mass, then it should also have a mother 3 −− glueball with a similar mass. The D(1285) may well be a 2 −+ glueball.
