We present the first observation of K^{-} and ϕ absorption within nuclear matter by means π^{-}-induced reactions on C W targets at an incident beam momentum 1.7 GeV/c studied with HADES SIS18/GSI. The double ratio (K^{-}/K^{+})_{W}/(K^{-}/K^{+})_{C} is found to be 0.319±0.009(stat)_{-0.012}^{+0.014}(syst) indicating a larger in heavier as compared lighter ones. measured ϕ/K^{-} ratios π^{-}+C π^{-}+W acceptance are equal 0.55±0.04(stat)_{-0.07}^{+0.06}(syst)...
A feasibility study has been performed in order to investigate the performance of HADES detector measure electromagnetic decays hyperon resonances $\Sigma(1385)^0$, $\Lambda(1405)$ and $\Lambda{\Lambda}(1520)$ as well production double strange baryon systems $\Xi^-$ $\Lambda\Lambda$ p+p reactions at a beam kinetic energy 4.5 GeV. The existing will be upgraded by new Forward Detector, which extends acceptance into range polar angles that plays crucial role for these investigations. analysis...
Pion-induced reactions provide unique opportunities for an unambiguous description of baryonic resonances and their coupling channels by means a partial-wave analysis. Using the secondary pion beam at SIS18, two-pion production in second resonance region has been investigated to unravel role $N(1520){\frac{3}{2}}^{\ensuremath{-}}$resonance intermediate $\ensuremath{\rho}$-meson production. Results on exclusive with one (${\ensuremath{\pi}}^{\ensuremath{-}}p$) two pions...
The HADES collaboration uses the e + − production as a probe of resonance matter produced in collisions at incident energies 1-3.5 GeV/nucleon GSI. Elementary reactions provide useful references for these studies and give information on Dalitz decays (R→Ne ). Such processes are sensitive to structure time-like electromagnetic baryon transitions kinematic range where (off-shell) vector mesons play crucial role. Results obtained proton-proton commissioning pion-beam experiment reported...
We present results of low-mass dielectron measurements from Au+Au collisions at √SNN = 2.4 GeV with HADES. The focus lies on the extraction effective temperature differential dilepton spectra and analysis azimuthal anisotropy virtual photons.
The well-defined information leakage of Encrypted Search Algorithms (ESAs) is predominantly analyzed by crafting so-called attacks. These attacks utilize adversarially known auxiliary data and the observed to attack an ESA instance built on a user's data. Known-data require be subset In contrast, sampled-data merely rely that is, in some sense, statistically close hence reflect much more realistic scenario where stems from publicly available source instead private
