摘要

Recently [see. V. V. Anisovich et al., Yad, Fiz. 63, 1489 (2000)], the K-matrix solutions for the wave I J~(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_(-250)~(+90)) are located. Based on these solutions, partial widths are determined for scalar-isoscalar states decaying into the channels ππ, K(K-bar), ηη, ηη', ππππ and corresponding decay couplings.
