Query: Phenomenology of Scalar Mesons   A separable potential model of three coupled channels (pion-pion,
kaon-antikaon and an effective four pion) has been constructed and applied in
the analysis of the isoscalar S-wave pion-pion and kaon-antikaon phase shifts
and inelasticities .A relatively narrow scalar resonance of mass 1400-1460 MeV
has been found. This resonance is consistent with the recent CERN observation
of an eventual scalar glueball at 1500 MeV. Other resonances at lower energies
like a wide sigma meson and a narrow f0(980) have been confirmed.
