The global polarization of {\Lambda} hyperons along the total orbital angular momentum a relativistic heavy-ion collision is presented based on high statistics data samples collected in Au+Au collisions at \sqrt{s_{NN}} = 2.4 GeV and Ag+Ag 2.55 with High-Acceptance Di-Electron Spectrometer (HADES) GSI, Darmstadt. This first measurement below strangeness production threshold nucleon-nucleon collisions. Results are reported as function centrality well hyperon transverse (p_T) rapidity (y_{CM})...

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.
In March 2019 the HADES experiment recorded 14 billion Ag+Ag collisions at √ S NN = 2.55 GeV as a part of FAIR phase-0 physics program. With capabilities to measure and analyze particles forming bulk matter, namely pions, protons light nuclei, well rare probes like dilepton decays vectormesons strange hadrons, allows study properties matter high densities in great detail. this contribution special focus is put on reconstruction weakly decaying hadrons.
Abstract HADES is a multi-purpose, charged-particle detector operated at the SIS18 synchrotron located GSI Helmholtz Center for Heavy Ion Research in Darmstadt, Germany. The provided ion beam energies of 1-2 A GeV are among lowest all currently running heavy-ion experiments and result highest baryon net-densities freeze-out case Au+Au collisions. At energy 1.23 GeV, particles containing strangeness produced below quasi-free NN threshold energy. Since missing has to be by collision system,...
In this contribution we present results from Au+Au collisions at √ S NN = 2.42 GeV as well Ag+Ag and 2.55 measured by HADES. We focus on three different observables: electromagnetic probes, collective bulk-matter phenomena strangeness production which are discussed in the following.
We aim to constrain the equation of state nuclear matter by comparing calculations with SMASH transport model directed and elliptic flow measurements for protons deuterons performed HADES collaboration in a systematic way. A momentum-dependent term is included potential which we show that it needed describe data. further incorporate simple symmetry present constraints on stiffness at saturation density potential. The are obtained performing Bayesian analysis such can also provide an...
In March 2019 the HADES experiment recorded 14 billion Ag+Ag collisions at √ s NN = 2.55 GeV as a part of FAIR phase-0 physics program. this contribution, we present and investigate our capabilities to reconstruct analyze weakly decaying strange hadrons hypernuclei emerging from these collisions. The focus is put on measuring mean lifetimes particles.
The double-differential production cross sections ${d}^{2}\ensuremath{\sigma}/d\mathrm{\ensuremath{\Omega}}dE$ for hydrogen isotopes and charged pions in the reaction of $p+^{93}\mathrm{Nb}$ at 3.5 GeV proton beam energy have been measured by high-acceptance dielectron spectrometer (HADES). Thanks to high acceptance HADES forward emission angles use its magnetic field, range could be significantly extended comparison with relatively scarce experimental data available literature. provide...
