“…[34,35], the decay of the glueball into pions turned out to be about 4 GeV, hence definitely too large to be detected. The numerical value is obtained by assuming that the dilaton saturates the gluon condensate [37]. If this were true, large-N c would badly fail in the scalar sector and one could never find such a broad glueball.…”

Abstract. Glueballs are predicted in various theoretical approaches of QCD (most notably lattice QCD), but their experimental verification is still missing. In the low-energy sector some promising candidates for the scalar glueball exist, and some (less clear) candidates for the tensor and pseudoscalar glueballs were also proposed. Yet, for heavier gluonic states there is much work to be done both from the experimental and theoretical points of view. In these proceedings, we briefly review the current status of research of glueballs and discuss future developments.
