Meson resonances in forward-angle photoproduction
Ł. Bibrzycki, P. Bydžovský, R. Kamiński +1
Assuming that the photoproduction at forward angles and high energies is dominated by one pion exchange we calculate the mass distributions for low partial waves.…
Dispersive analysis of the -, -, -, and -wave amplitudes
P. Bydžovský, R. Kamiński, V. Nazari
A reanalysis of amplitudes for all important partial-waves below about 2 GeV is presented. A set of once subtracted dispersion relations with imposed crossing symmetry conditi…
Effect of the channel and interference phenomena in the two-pion transitions of charmonia and bottomonia
Yu. S. Surovtsev, P. Bydžovský, T. Gutsche +3
The basic shape of di-pion mass spectra in the two-pion transitions of both charmonia and bottomonia states is explained by an unified mechanism based on contributions of the ,…
The interference effects of multi-channel pion-pion scattering contributions to the final states of - and -meson family decays
Yu. S. Surovtsev, P. Bydžovský, T. Gutsche +3
It is shown that the basic shape of dipion mass distributions in the two-pion transitions of both charmonia and bottomonia states are explained by an unified mechanism based on the…
Effect of coupled channels of the multi-channel pion-pion scattering in two-pion transitions of the mesons
Yu. S. Surovtsev, P. Bydžovský, T. Gutsche +3
The effect of isoscalar S-wave processes is considered in the analysis of data (from the ARGUS, CLEO, CUSB, Crystal Ball, Belle, BABAR collaborations) on…
Modified amplitude with pole
P. Bydžovský, R. Kamiński, V. Nazari
A set of well known once subtracted dispersion relations with imposed crossing symmetry condition is used to modify unitary multichannel (, , and ) and ($…
The effect of multi-channel pion-pion scattering in decays of the -family mesons
Yu. S. Surovtsev, P. Bydzovsky, T. Gutsche +3
The effect of isoscalar S-wave multi-channel pion-pion scattering () is considered in the analysis of data on decays of the -meson family -- $Υ(2S)\toΥ(1S)π…
Direct vs. final state tensor meson photoproduction - amplitude analysis
Ł. Bibrzycki, R. Kamiński
Tensor meson photoproduction is described as either a direct production process or a consequence of the final state ππinteractions. We calculate the mass distributions for selected…
Can parameters of f_0-mesons be determined correctly analyzing only pion-pion scattering?
Yu. S. Surovtsev, P. Bydzovsky, R. Kaminski +2
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 app…
Parameters of scalar resonances from the combined analysis of data on processes and decays
Yu. S. Surovtsev, P. Bydzovsky, R. Kaminski +2
A combined analysis of data on isoscalar S-wave processes and on decays from the DM2, Mark III and BESIII collaborations is pe…
On nature of scalar and tensor mesons from the analysis of processes pi-pi-> pi-pi, K-Kbar, eta-eta
Yu. S. Surovtsev, R. Kaminski, D. Krupa +1
Analysis of the isoscalar S- and D-waves of processes pi-pi-> pi-pi, K-Kbar, eta-eta is carried out aimed at studying the status and QCD nature of scalar and tensor mesons below 2…
