Description

I will present quenched lattice calculations to support the existence of sigma(600) as a tetraquark mesonium and a_0(1450) as a q \bar q state. Based on these results and the latest glueball calculation, a pattern of light scalar mesons seems to emerge with two flavour SU(3) nonets and a fairly pure glueball.
