Calculations within QCD (lattice and sum rules) find the lightest glueball to be a scalar with
mass in the range of about 1000–1700 MeV. Several phenomenological investigations are …

The isosinglet scalar mesons f 0 (1710), f 0 (1500), f 0 (1370) and their mixing are studied.
We employ two recent lattice results as the starting point; one is the isovector scalar meson a …

A systematic enumeration of the glueball spectrum of QCD and other SU (n) gauge theories
yields JPC= odd−+ even+−, and 0−− states in addition to the usual quark model states …

We show that the newly discovered scalar meson f0 (1500) at LEAR has properties
compatible with the lightest scalar glueball predicted by lattice QCD and incompatible with a …

We discuss the theoretical expectations and phenomenological evidence for the lightest
glueballs and the members of the meson nonet with quantum numbers J^PC=0^++. We …

Glueballs, hybrids and multiquark states are predicted as bound states in models guided by
quantum chromo dynamics (QCD), by QCD sum rules or QCD on a lattice. Estimates for the …

We compute from lattice QCD in the valence (quenched) approximation the partial decay
widths of the lightest scalar glueball to pairs of pseudoscalar quark-antiquark states. These …

The spectrum of bound states of gluons is discussed within the MIT bag model. We argue
that (1) contrary to previous analysis there is no light exotic 1−+ state in the two gluon …
