The processes pp®pp, K[`K] and hh, with IGJPC = 0+0++, are analysed
by means of simultaneous coupled-channel analysis of all available data. The
investigation is focussed on the properties of the f0(665), f0(980),
f0(1370), f0(1500) and f0(1710) states with the
aim to determine their quark-gluonic content. The analysis supports the
existence of f0(665) as a very broad resonance. It suggests further
to see the f0(980) state as predominantly the hh bound state. The quark content of other states is inferred and f0(1500)
appears as a mixed state with dominant glueball component.
