NuSym23, XIth International Symposium on Nuclear Symmetry Energy

We review the current status of studies related to the equation of state as extracted from HADES data and will discuss future perspectives in heavy-ion runs at lower energies.

The study of strongly interacting matter under extreme conditions is one of the most important topics in the exploration of Quantum Chromodynamics (QCD).

In this talk, we present new measurements by the High Acceptance DiElectron Spectrometer (HADES) at GSI Helmholtzzentrum für Schwerionenforschung, relating to flow phenomena at high nuclear densities. HADES provides a large acceptance,...

Constraining the equation of state (EOS) of dense symmetric nuclear matter has been the goal of numerous experimental heavy-ion efforts worldwide, including the early experiments at the AGS and SPS, the currently ongoing efforts such as the Beam Energy Scan program at RHIC and the HADES experiment at GSI, and future experiments such as the Compressed Baryonic Matter experiment at FAIR. Beyond...

Within the framework of the quantum molecular dynamics transport model, the pion production and constraint of the high-density symmetry energy in heavy-ion collisions near threshold energy have been thoroughly investigated. The energy conservation in the decay of resonances and reabsorption of pions in nuclear medium are taken into account. The isospin and momentum dependent hyperon-nucleon...

Rapidity dependence of directed flow ($v_1$) and elliptic flow ($v_2$) were analyzed for various particles, including proton, deuteron, triton, $\mathrm{^{3}He}$, and $\mathrm{^{4}He}$ observed in collisions involving $\mathrm{^{132}Sn+{}^{124}Sn}$ and $\mathrm{^{108}Sn+{}^{112}Sn}$ collisions at 270 $\mathrm{MeV/u}$.
The flow was larger for heavier charged particles, i.e.,
the slope of...
