Hadrons have been suggested as sensitive probes for the medium properties of nuclear matter created in heavy-ion collisions. A dense baryon-rich medium is formed during collisions at center-of-mass energies of a few-GeV. Since (anti-)strange hadrons and anti-protons are produced near or below the threshold, their phase space distribution and yield ratios may provide strong constraints on the...

In this report, we present measurements of $^3_\Lambda H$ and $^4_\Lambda H$ in Ag+Ag collisions at $\sqrt{s_{NN}}$ = 2.55 GeV, conducted with the HADES experiment at GSI. While at RHIC and LHC energies hypernuclei production is typically discussed with a focus on two scenarios, statistical production in full equilibrium versus production via coalescence, at SIS energies, the spatial region of...

Understanding strangeness enhancement in proton-proton (pp) collisions at the LHC remains a challenge for hadronization models. Recent observations of the $\Omega_\mathrm{c}^0$ baryon indicate that a substantial fraction of the detected Ω baryons may originate from the decay of charm hadrons, e.g. from $\Omega_\mathrm{c}^0 \rightarrow \Omega^- + \pi^+$. However, the unknown absolute branching...

One of the unresolved issues in hadron–hadron collisions is the microscopic understanding of how light (anti)(hyper)nuclei are created. Several differential measurements of (anti)(hyper)nuclei yields, momentum distributions, and fluctuations have been carried out in pp, p–A, and A–A collisions at ultra-relativistic energies. Comparisons to models based on statistical hadronization or nucleon...

Strangeness production in high-energy hadronic and nuclear collisions continues to be one of the central topics in the study of strongly interacting matter. The data collected by the NA61/SHINE experiment at the CERN SPS North Area allows for a comprehensive scan of the strangeness production across various collision energies and system sizes.
This presentation will focus on the new...

The study of exotic hadrons has long been a topic of great interest for the understanding of Quantum Chromodynamics (QCD). As one of the light exotic hadrons, the structure and constituent quark content of $f_0(980)$ have been debated for decades, with theories suggesting it could be a tetraquark state ($s\bar sq\bar q$) or a hadronic molecule ($K\bar K$). Recently, the CMS experiment has...
