We present an analysis of proton number fluctuations in $\sqrt{s_{NN}}$ = 2.4 GeV Au+Au collisions measured with the High-Acceptance DiElectron Spectrometer (HADES) at GSI. With help extensive detector simulations done IQMD transport model events including nuclear clusters, various nuisance effects influencing observed cumulants have been investigated. Acceptance and efficiency corrections applied as a function fine grained rapidity transverse momentum bins, well considering local track...
Flow coefficients $v_{n}$ of the orders $n = 1 - 6$ are measured with High-Acceptance DiElectron Spectrometer (HADES) at GSI for protons, deuterons and tritons as a function centrality, transverse momentum rapidity in Au+Au collisions $\sqrt{s_{NN}} 2.4$ GeV. Combining information from flow all allows to construct first time, collision energies few GeV, multi-differential picture angular emission pattern these particles. It reflects complicated interplay between effect central fireball...

We present data on charged kaons (K+-) and {\phi} mesons in Au(1.23A GeV)+Au collisions. It is the first simultaneous measurement of K central heavy-ion collisions below a kinetic beam energy 10A GeV. The {\phi}/K- multiplicity ratio found to be surprisingly high with value 0.52 +- 0.16 shows no dependence centrality collision. Consequently, different slopes K+ K- transverse-mass spectra can explained solely by feed- down, which substantially softens mesons. Hence, contrast commonly adapted...
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.
The tagged quasi-free np→npπ+π− reaction has been studied experimentally with the High Acceptance Di-Electron Spectrometer (HADES) at GSI a deuteron incident beam energy of 1.25 GeV/nucleon (s∼2.42 GeV/c for collision). For first time, differential distributions solid statistics π+π− production in np collisions have collected region corresponding to large transverse momenta secondary particles. invariant mass and angular are compared different models. This comparison confirms dominance...

By comparing experimental correlation function to model calculations, a source size for pairs...
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)...
We report on the investigation of $\mathrm{\ensuremath{\Delta}}$(1232) production and decay in proton-proton collisions at a kinetic energy 1.25 GeV measured with HADES. Exclusive dilepton channels $pp{e}^{+}{e}^{\ensuremath{-}}$ $pp{e}^{+}{e}^{\ensuremath{-}}\ensuremath{\gamma}$ have been studied compared partial-wave analysis hadronic $pp{\ensuremath{\pi}}^{0}$ channel. They allow to access both...
We present high-statistic data on charged pion emission from Au+Au collisions at $\sqrt{s_{\rm{NN}}}$ = 2.4 GeV (corresponding to $E_{beam}$ 1.23 A GeV) in four centrality classes the range 0 - 40$\%$ of most central collisions. The are analyzed as a function transverse momentum, mass, rapidity, and polar angle. Pion multiplicity per participating nucleon decreases moderately with increasing centrality. angular distributions found be non-isotropic even for event class. Our results fit well...
High-statistics $\pi^-\pi^-$ and $\pi^+\pi^+$ femtoscopy data are presented for Au+Au collisions at $\sqrt{s_\mathrm{NN}}=2.4$ GeV, measured with HADES SIS18/GSI.

A substantial charge-sign difference source radii is found, particularly pronounced low extracted parameters agree...
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...
We report on the investigation of dielectron production in tagged quasi-free neutron-proton collisions by using a deuteron beam kinetic energy 1.25GeV/u impinging liquid hydrogen target. Our measurements with HADES confirm significant excess $e^{+}e^{-}$ pairs above $\pi^{0}$ mass exclusive channel $dp \rightarrow npe^{+}e^{-}(p_{spect})$ as compared to $ ppe^{+}e^{-}$ measured proton-proton at same energy. That points different bremsstrahlung mechanisms. Two models were evaluated for role...
