Add   Effect of the KK̅ and ηη channels and interference phenomena in the two-pion and KK̅ transitions of charmonia and bottomonia
Authors: Bydžovský, Petr | Gutsche, Thomas | Kamiński, Robert | Lyubovitskij, Valery E. | Nagy, Miroslav | Surovtsev, Yurii S.
Source: Physical Review D. 2018. Vol. 97, № 1. P. 014009-1-014009-13
Type: статьи в журналах

Description: It is shown that the basic shape of dipion and KK̅ mass spectra in decays J/ψ→ϕ(ππ,KK̅), ψ (2S)→J/ψππ, Y(4260)→J/ψ π π and in the two-pion transitions of bottomonia states are explained by an unified ... More

Description: The basic shape of di-pion mass spectra in the two-pion transitions of both charmonia and bottomonia states is explained by a unified mechanism based on contributions of the ππ, KK̅, and ηη coupled ch ... More
Add   Unified description of BABAR and Belle data on the bottomonia decays Υ(mS)→Υ(nS)π+π-

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
