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 analysis we extend our recent study of low-lying (m=2,3) radial excitations of bottomonia to modes involving higher (m=4,5) excited states. Similarly as for the data on lower radial excitations, we confirm that the data for higher radially excited states from the BABAR and Belle collaborations can be…

Effect of the ηη channel and interference phenomena in the two-pion transitions of charmonia and bottomonia

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, KK , and ηη coupled

Insights into Zb(10610) and Zb(10650) from dipion transitions from ϒ(10860)

The dipion transitions $\mathrm{\ensuremath{\Upsilon}}(10860)\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}\mathrm{\ensuremath{\Upsilon}}(nS)$ ($n=1$, 2, 3) are

Effect of the $K\overline{K}$ and $\eta\eta$ channels and interference phenomena in the two-pion and $K\overline{K}$ transitions of charmonia and bottomonia

It is shown that the basic shape of dipion and $K\overline{K}$ mass spectra in decays $J/\psi\to\phi(\pi\pi,K\overline{K})$, $\psi(2S)\to J/\psi\,\pi\pi$, $Y(4260)\to J/\phi~\pi\pi$ and in the



Observation of two charged bottomoniumlike resonances in Υ(5S) decays.

The observation of two narrow structures in the mass spectra of the π(±)Υ(nS) and π (±)h(b)(mP) pairs that are produced in association with a single charged pion in Υ(5S) decays is reported.

Role of multichannel pi pi scattering in decays of bottomia

The effect of isoscalar S-wave multichannel pi pi -> pi pi, K antiK, eta eta scattering is considered in the analysis of decay data of the Upsilon-mesons. We show that when allowing for the final

On lower scalar quark-antiquark nonets

Two-and three-channel analyses of experimental data on the coupled processes ππ → ππ, k, ηη in the channel with IGJPC = 0+0++ are carried out and discussed. In a model-independent approach,


The reaction e+e-+e+e-7r07r0 has been analyzed using 97 pb-’ of data taken with the Crystal Ball detector at the DORIS II e+estorage ring at beam energies around 5.3 GeV. For the first time we have

Can parameters of f(0)-mesons be determined correctly analyzing only pi pi scattering?

The coupled processes -- the pion-pion scattering and pi pi --> K antiK in the I^GJ^{PC}=0^+0^{++} channel -- are analyzed (both separately and combined) in a model-independent approach based on

Phenomenological sigma models.

The question of the phenomenological description of the broad scalar resonances compatible with chiral symmetry and unitarity is discussed within the framework of the linear [sigma] model and the simplest unitarization scheme is shown.

Bottomonium dipion transitions

Dipion transitions of the subthreshold bottomonium levels {upsilon}(nS){yields}{upsilon}(n{sup '}S){pi}{pi} with n>n{sup '}, n=2, 3, 4 n{sup '}=1, 2 are studied in the framework of the chiral decay

Nature of the scalar-isoscalar mesons in the uniformizing-variable method based on analyticity and unitarity

The experimental data on the processes $\pi\pi\to\pi\pi,K\bar{K},\eta\eta,\eta\eta^\prime$ in the $I^GJ^{PC}=0^+0^{++}$ channel have been jointly analyzed to study the status and nature of the $f_0$.
