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...

The search for a first-order phase transition in strongly interacting matter is one of the major objectives exploration diagram quantum chromodynamics (QCD). In present work we investigate dilepton radiation from hot and dense fireballs created Au-Au collisions at projectile energies 1--2 $A\mathrm{GeV}$ potential signatures transition. Toward this end, employ hydrodynamic simulation with two different equations state, without latter constrained by susceptibilities vanishing chemical...
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. The experimental correlation functions allow the determination of space-time extent corresponding emission sources via a comparison to models. source, parametrized as three-dimensional Gaussian distribution, is studied in dependence on pair transverse momentum, azimuthal angle respect reaction plane, collision centrality beam...
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...
In this letter we report the first multi-differential measurement of correlated pion-proton pairs from 2 billion Au+Au collisions at sNN=2.42 GeV collected with HADES. energy regime population Δ(1232) resonances plays an important role in way is distributed between intrinsic excitation and kinetic hadrons fireball. The triple differential d3N/dMπ±pdpTdy distributions π±p have been determined by subtracting πp combinatorial background using iterative method. invariant-mass mass region show...
Electromagnetic radiation is emitted during the whole course of a heavy-ion collision and can escape from zone without further interactions.This makes it an ideal tool to study properties hot dense QCD matter.To model space-time evolution at SIS energies coarse-graining approach used convert transport simulations into meaningful temperatures densities.These parameters serve as input for determination pertinent thermal dileptons based on in-medium ρ spectral function that describes available...
Multi-differential measurements of dilepton spectra serve as a unique tool to characterize the properties matter in interior hot and dense fireball created heavy-ion collisions. An important property virtual photons is their spin polarization defined rest frame photon with respect chosen quantization axis. Microscopic calculations in-medium electromagnetic spectral functions have mostly focused on integrated yields which are proportional sum longitudinal transverse components photon’s...
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 spectra of dileptons radiated from the fireballs formed in high-energy heavy-ion collisions have been successfully used to investigate key properties hot and dense QCD matter. In this paper we study polarization observables which thus far received little attention. Microscopic calculations in-medium electromagnetic spectral functions mostly focused on integrated yields are proportional sum longitudinal transverse components virtual photon's selfenergy. Photon results difference these...
