Light scalar meson spectrum

We discuss the classification of the light scalar mesons with mass below 2 GeV into q (q) over bar nonets and glueballs. The information on production and decay of these states, in particular recent information on the f(0)(980), f(0)(400 - 1200) (or sigma(600)) and f(0)(1500) is considered. Although the data are not yet very precise the recent information is in favour of the previously developed scheme which includes f(0)(980), a(0)(980), K-0* (1430), f(0)(1500) into the lightest scalar nonet. The glueball in this approach appears as broad object around I GeV. Alternative schemes find the glueball at somewhat higher mass or suggest his mixing with q (q) over bar states spread over a similar mass range. We do not see sufficient evidence yet for a light scalar nonet below 1 GeV around a a(600) resonance.
