The glueball among the light scalar mesons
Abstract
In our phenomenological analysis of the spectroscopy of light scalar mesons we do not find compelling evidence for the existence of the low mass (900) or σ(600) states nor for f0(1370) as single resonance. If the f0(980) and and f0(1500) are taken as members of the q qbar nonet there remains a broad object formed by f0(400-1200) and f0(1370) which is a glueball candidate gb(1000).
