We present an analysis of the Lambda(1405) resonance produced in reaction p+p->Sigma^{pm}+pi^{mp}+K+p at 3.5 GeV kinetic beam energy measured with HADES GSI. The two charged decay channels -> Sigma^{\pm}+pi^{\mp} have been reconstructed for first time p+p collisions. efficiency and acceptance-corrected spectral shapes show a peak position clearly below 1400 MeV/c^2. find total production cross section sigma_{Lambda(1405)}=9.2 +- 0.9 0.7 +3.3-1.0 mub. its polar angle distribution suggests...
We present first data on sub-threshold production of K0 s mesons and Λ hyperons in Au+Au collisions at $\sqrt{s_{NN}}$ = 2.4 GeV. observe an universal scaling hadrons containing strangeness, independent their corresponding thresholds. Comparing the yields, scaling, shapes rapidity pt spectra to state-of-the-art transport model (UrQMD, HSD, IQMD) predictions, we find that none latter can simultaneously describe all observables with reasonable \c{hi}2 values.
Our answer to the question posed in title is: probably no. In this work we show that it is rather unlikely structure $X(2265)$ reported by DISTO collaboration corresponds a kaonic nuclear bound state. The main argumentation based on repetition of analysis HADES data sample, containing p+p reactions at 3.5 GeV. We further discuss many aspects connection with $pK^{+}\Lambda$ final state and $\Lambda(1405)$-resonance. results evidence possible problematics interpretation data.
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 decay of Λ(1405) into Σ 0 π was studied in p + collisions at E Kin =3.5 GeV , measured by the High Acceptance Di-Electron Spectrometer (HADES). To extract line shape Λ(1405), special techniques have been developed to describe misidentification background and contributions different production channels.
The HADES collaboration has searched for the anti-kaonic nuclear cluster “ppK−” in p+p collisions by its decay into pΛ. In course of this analysis several cross checks had to be performed. This report discusses two examples thereof. one test it was checked whether presence background events could introduce a bias on applied partial wave analysis. second item discussed here is extraction total pK+Λ production section necessary derive absolute upper limit section.
Article 67 Quantifizierung von Stenosen der Herzkranzgefäße durch digitale Bildauswertung was published on January 1, 1981 in the journal Biomedical Engineering / Biomedizinische Technik (volume 26, issue s1).
The assessment of stenotic arteries is an important parameter for the diagnosis coronary heart disease and indication a bypass operation. A system has been developed to digitize process frames from 35 mm- cinecardiographic films on computer. Vessels filled with contrast medium are recognized automatically by their typical density profiles. contour finding takes into account special edge form projected boli. When bolus contours determined degree diameter narrowing can easily be calculated....
The normal flow values through healthy or moderately narrowed coronary arteries, which had been determined by a new method of cine radiography, together with computer, were published in this Journal 1976. In the present paper we report results further studies velocity and volume high-grade artery stenosis severity III III--IV. Compared obtained on mildly stenosed measurements at rest severely coronaries showed an almost constant flow. first aorto-coronary vein graft measurement are described.
We present an analysis of the Lambda(1405) resonance in p+p reactions at a kinetic beam energy 3.5 GeV, measured by High Acceptance Di-Electron Spectrometer (HADES). The is reconstructed two charged decay channels Sigma^(+/-) pi^(-/+), with help kinematic refit, which improves mass resolution. high misidentification pions and protons as kaons required development sophisticated sideband analysis, can describe background quite well.
We report, here, on the progress in our analysis of data taken with HADES detector. As described last year’s GSI Scientific report [1], we have reconstructed ∼20.000 pKΛ events that were produced p+p reactions at a beam kinetic energy 3.5 GeV. To describe measured observables employed PWA [2]. In this several transition amplitudes, including production final state via decay various N* resonances, fitted to events. A good description was obtained and presented [1]. now performed more refined...
