Description: The effect of isoscalar S-wave multichannel ππ→ππ, KK¯¯,ηη scattering is considered in the analysis of decay data of the Υ-mesons. We show that when allowing for the final state interaction contributi ... More

Description: We present a unified analysis of the decays of bottomonia Υ(mS)→Υ(nS)ππ (m>n, m=2,3,4,5, n=1,2,3), charmonia J/ψ→ϕ(ππ,KK¯), ψ(2S)→J/ψππ, and the isoscalar S-wave processes ππ→ππ,KK¯,ηη. In this analys ... More
