The hadronic reaction pp→Σ+K0p was measured exclusively at a beam momentum of 2.95GeV/c using the TOF detector COSY storage ring. A narrow peak observed in invariant mass spectrum K0p-subsystem 1530±5MeV/c2 with significance 4–6 standard deviations, depending on background assumptions. upper limit 18±4MeV/c2 (FWHM) for its width is given by experimental resolution. corresponding total cross section estimated to be about 0.4±0.1(stat)±0.1(syst) μb. Since resonance this subsystem must have...
This paper reports results on simultaneous measurements of the reaction channels pp $ \rightarrow$ pK + \Lambda$ and \Sigma^{0}_{}$ at excess energies 204, 239, 284MeV ( 127, 162, 207MeV . Total differential cross-sections are given for both reactions. It is concluded from measured total that high-energy limit cross-section ratio almost reached an energy only about 200MeV. From distributions observed in overall CMS as well Jackson helicity frames, a significant contribution interfering...
The cross section for the production of ω mesons in proton–proton collisions has been measured a previously unexplored region incident energies. Cross sections σ=(7.5±1.9) μb and σ=(30.8±3.4) (with 20% systematic uncertainties) were extracted at ϵ=92 MeV 173 excess energy above threshold, respectively. angular distribution ϵ=173 is strongly anisotropic, demonstrating importance partial waves beyond pure s-wave this energy.
We present the first determination of energy-dependent amplitudes N⁎ resonances extracted from their decay in KΛ pairs p+p→pK+Λ reactions. A combined Partial Wave Analysis seven data samples with exclusively reconstructed events measured by COSY-TOF, DISTO, FOPI and HADES Collaborations fixed target experiments at kinetic energies between 2.14 to 3.5 GeV is used determine amplitude resonant non-resonant contributions into associated strangeness final state. The contribution masses 1650...
The reaction $ pp\to pp\bf ω$ was investigated with the TOF spectrometer, which is an external experiment at accelerator COSY (Forschungszentrum Jülich, Germany). Total as well differential cross sections were determined excess energy of $93 MeV$ ($p_{beam}=2950 MeV/c$). Using total section $(9.0\pm 0.7 \pm1.1) μb$ for ppω$ here and existing data $pp\to ϕ$, ratio $\mathcal{R}_{ϕ/ω}=σ_ϕ/σ_ω$ turns out to be significantly larger than expected by Okubo-Zweig-Iizuka (OZI) rule. uncertainty this...
The $\stackrel{P\vec}{p}p\ensuremath{\rightarrow}p{K}^{+}\mathrm{\ensuremath{\Lambda}}$ reaction has been measured with the COSY-TOF detector at a beam momentum of $2.7\phantom{\rule{0.16em}{0ex}}\mathrm{GeV}/c$. polarized proton enables measurement analyzing power by asymmetry produced kaon $({A}_{N}^{K})$. This observable allows $p\mathrm{\ensuremath{\Lambda}}$ spin triplet scattering length to be extracted for first time model independently from final state interaction in reaction....
