چکیده
A partial-wave analysis of the decay J/ψ → K+ K−π0 made using (223.7 ± 1.4) 106 events collected with BESIII detector in 2009 [1] will be presented and discussed. We report most precise measurements K*(892)± K2*(1430)± mass width. The reveals contributions from K2*(1980)± K4*(2045)± for first time decays. Two resonance signals decaying to K+K− are also observed their possible interpretations Results include branching fractions decays through intermediate states a high precision measurement B(J/ψ K−π0). results differ significantly those reported earlier by BESII BABAR Collaborations.

Partial wave analysis in K - matrixformalismS
A description is given of the K-matrix formalism. The formalism, which is normally applied to two-body scattering processes, is generalized to production of two-body channels with nal-state interactions. A multi-channel treatment of production of resonances has been worked out in the P-vector approach of Aitchi-son. An alternative approach, derived from the P-vector, gives the production amplit...
متن کاملPartial Wave Analysis of J / ψ → γ ( K + K − π + π − )
BES data on J/ψ → γ(KKππ) are presented. The KK̄ contribution peaks strongly near threshold. It is fitted with a broad 0 resonance with mass M = 1800 ± 100 MeV, width Γ = 500 ± 200 MeV. A broad 2 resonance peaking at 2020 MeV is also required with width ∼ 500 MeV. There is further evidence for a 2 component peaking at 2.55 GeV. The non-KK̄ contribution is close to phase space; it peaks at 2.6 GeV...
متن کاملUpdate on Partial-Wave Analysis
Partial-wave analysis is one step in a process connecting experimental measurements to the N states we are studying. Progress has been made in the area of ‘model-independent’ analysis. However, more model-dependent approaches are needed to cover broader energy ranges. An example of the problems faced by these more ambitious analyses is given.
متن کاملQuantum scattering problem without partial-wave analysis
We have suggested a method for treating different quantum few-body dynamics without usual partial-wave analysis. With this approach new results were obtained in the physics of ultracold atom-atom collisions and ionization and excitation/deexitation of helium ions. The developed computational scheme opens new possibilities for analysis the actual problem of ultracold atom wave-packets collisions...
متن کاملAmbiguities in the partial-wave analysis of pseudoscalar-meson photoproduction.
Ambiguities in the partial-wave analysis of pseudoscalar-meson photoproduction Abstract Ambiguities in pseudoscalar-meson photoproduction, arising from incomplete experimental data, have analogs in pion-nucleon scattering. Amplitude ambiguities have important implications for the problems of amplitude extraction and resonance identification in partial-wave analysis. The effect of these ambiguit...
