| 330 | _aThe effect of isoscalar S-wave processes ππ→ππ,KK¯,ηηππ→ππ,KK¯,ηη is considered in the analysis of data (from the ARGUS, CLEO, CUSB, Crystal Ball, Belle, BABAR collaborations) on the bottomonia decays - Υ(mS)→Υ(nS)ππΥ(mS)→Υ(nS)ππ (m>n,m=2,3,4,5,n=1,2,3m>n,m=2,3,4,5,n=1,2,3). It is shown that the dipion mass spectra of these decays are explained by the unified mechanism related to the contribution of the multichannel ππππ scattering in the final states of these reactions. Since in the analysis the multichannel ππππ-scattering amplitudes did not change in comparison with the ones in our combined analysis of data on the multichannel ππππ scattering and on the charmonia decays - J/ψ→ϕ(ππ,KK¯¯¯¯¯)J/ψ→ϕ(ππ,KK¯) and ψ(2S)→J/ψ(ππ)ψ(2S)→J/ψ(ππ) (from the Crystal Ball, DM2, Mark II, Mark III, and BES II) - the results confirm all our earlier conclusions on the scalar mesons. | ||
