Evidence for the neutron-rich hypernucleus $_{\ensuremath{\Lambda}}^{6}\mathrm{H}$ is presented from FINUDA experiment at $\mathrm{DA}\ensuremath{\Phi}\mathrm{NE}$, Frascati, studying $({\ensuremath{\pi}}^{+},{\ensuremath{\pi}}^{\ensuremath{-}})$ pairs in coincidence ${K}_{\mathrm{stop}}^{\ensuremath{-}}+^{6}\mathrm{Li}\ensuremath{\rightarrow}_{\ensuremath{\Lambda}}^{6}\mathrm{H}+{\ensuremath{\pi}}^{+}$ production reaction followed by...
We report stopping powers of hydrogen and helium for antiprotons kinetic energies ranging from about 0.5 keV to 1.1 MeV. The Barkas effect, i.e., a difference in the power protons same energy material, shows up clearly either gases. Moreover, below \ensuremath{\approx}0.5 there is indirect evidence an increase antiproton power. This "nuclear" losses quasimolecular interactions, fair agreement with theoretical predictions.
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 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 cross-section for annihilation on Fe from 100 to 531 MeV/c was measured by means of a layered absorption detector. cross-sections are related the free N simple A2/3 scaling law, indicating surface process.
This paper reports results from a study of the reaction pp → pK0Σ+ at beam momenta p = 2950, 3059, and 3200 MeV/c (excess energies ε 126, 161, 206 MeV. Total cross-sections were determined for all energies; set differential (Dalitz plots; invariant-mass spectra two-body subsystems; angular distributions final-state particles; in helicity Jackson frames) are presented 161 The total proportional to volume available three-body phase space indicating that transition matrix element does not...
