Soon after, they calculated that the lightest glueball would have a mass (expressed in energy units) of about 1,707 megaelectronvolts (MeV).
To determine whether such a glueball would stick together long enough to be observed in a particle accelerator, the researchers calculated the glueball's rate of decay into different combinations of other particles.
The calculation demonstrated that a glueball has a sufficiently long lifetime for the particle to be detectable.
The result suggests that glueballs may be observed in particle accelerators when electrons or protons and their antimatter counterparts collide at high energies.

The second set contains the search for a monopole by means of its direct interaction with charge, glueballs, pentaquarks, nuggets of Strange Quark Matter (SQM) and the Higgs boson.
* Several decades ago, claims concerning the existence of glueballs have been published by QCD supporters (see [11], p.
For instance, the probability of creation of glueballs scales as O([N.sup.2.sub.c]), while that of mesons scales as O([N.sub.c]) [6,7].
One way of creating this r potential was found by making a new force nature that requires the QCD "equivalent of the photon", the gluon, to not only mediate the force as does the photon, but also participates in it (requires glueballs to exist).
