The σ and f0(980) from Ke4⊕ππ, γγ scatterings, J/ψ, ϕ→γσB and Ds→lνσB

We extract the pole positions, hadronic and γγ widths of σ and f0(980), from ππ and γγ scattering data using an improved analytic K-matrix model. Our results favour a large gluon component for the σ and a s¯s or/and gluon component for the f0(980) but neither a large four-quark nor a molecule component. Gluonium σB production from J/ψ, ϕ radiative and Ds semi-leptonic decays are also discussed.
