Abstract
Recently [see V.V. Anisovich et al., Yad. Fiz. 63, 1489 (2000)], the K-matrix solutions for the wave IJ PC=00++ were obtained in the mass region 450–1900 MeV, where four resonances f 0(980), f 0(1300), f 0(1500), f 0(1750) and the broad state f 0(1530 +90−250 ) are located. Based on these solutions, partial widths are determined for scalar-isoscalar states decaying into the channels ππ, KK ηη, ηη′, ππππ and corresponding decay couplings.
