One main motivation of the Beam Energy Scan (BES) program at RHIC is to search for the QCD critical point and the onset of deconfinement. Strangeness production has been suggested as a sensitive probe to the early dynamics of the deconfined matter created in heavy-ion collisions. Ratios of particle yields involving strange particles are often utilized to study various properties of the nuclear...
The pseudorapidity distributions and anisotropic flow coefficients of charged particles produced in heavy ion collisions are key observables that characterize the initial conditions and subsequent hydrodynamic evolution of the quark-gluon plasma. Recent LHC Run 3 lead-lead (PbPb) data collected at a center-of-mass per nucleon pair of $\sqrt{s_{_{\mathrm{NN}}}} = 5.36$~TeV allow the study of...
The investigation of the quark content of hadrons has been a major goal of non-perturbative strong interaction physics. In the last decade, several resonances in the mass range 1000-2000 MeV/$c^2$ have emerged that cannot be explained by the quark model. The internal structure of exotic resonances such as $\rm f_0$, $\rm f_1$, and $\rm f_2$ is currently unknown. Different scenarios are...
Measurements of the dynamical correlations between neutral and charged kaons in central Pb-Pb collisions at $\sqrt{s_{NN}} = 2.76$ TeV by the ALICE Collaboration display anomalous behavior relative to conventional heavy-ion collision simulators. We consider other conventional statistical models, none of which can reproduce the magnitude and centrality dependence of the correlations. The data...
Hadronic resonances have typical lifetimes that are comparable to that of the hadron gas phase created in the late stages of high-energy nuclear collisions. Therefore, a significant fraction of resonances decays inside a high-density medium and their decay daughters may rescatter with other hadrons destroying their initial kinematic correlations. A competing effect is resonance regeneration...
Measurements of light flavour particle production in small collision systems at the LHC energies have shown the onset of features (e.g. radial flow) that resemble what is typically observed in nucleus-nucleus collisions and attributed to the formation of a strongly interacting medium.
By performing more differential studies and analysing smaller fractions of the visible cross section the...
Particle correlations are a powerful tool to study the properties of the bulk nu-
clear matter produced in relativistic heavy ion collisions. The momentum cor-
relations between identical particles originating from the same particle-emitting
source, referred to as the Bose-Einstein correlations, measure scales that are
related to the geometrical size of the source. The two-particle...
The ALICE Collaboration presents a new experimental approach to explore the interactions in three-hadron systems by analyzing femtoscopic correlation functions of deuteron-hadron pairs produced in high-multiplicity pp collisions at $\sqrt{s}$ = 13 TeV and in Pb--Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ $\mathrm{TeV}$ at the LHC. The measured p-d correlation function can only be explained if...
The investigation of the production mechanism of light (anti)(hyper)nuclei in ultrarelativistic hadronic collisions is one of the main topics in modern nuclear physics. The ALICE Collaboration has significantly contributed to this specific field of research with systematic measurements of the production of (anti)(hyper)nuclei in different collision systems and centre-of-mass energies provided...
We present first results for light and heavy flavor high-$p_T$ hadron suppression from a short path length corrected energy loss model in $p+p$, $p+A$, and $A+A$ collisions at RHIC and the LHC. We find that the short path length corrections to final state radiative energy loss for light flavor hadrons predict nontrivial enhancement such that high multiplicity $R_{pA} > 1$, consistent with...

The formation of weakly bound clusters and hypernuclei in the hot and dense environment at midrapidity is one of the surprising phenomena observed experimentally in heavy-ion collisions from low SIS to ultra-relativistic LHC energies. This is also known as the `ice in a fire'...
The recent measurements of NA61/SHINE at the CERN SPS revealed a large violation of isospin symmetry. The ratio of charged to neutral kaons was measured to be 1.22 ± 0.06 in Ar+Sc collisions at 75A GeV/c. This contribution will present the experimental details of this intriguing result. It will also compare it to the world data on charged to neutral kaons ratio in nucleus-nucleus collisions....
In this contribution we will discuss the production of $\Sigma^0$ baryons in Ag+Ag collisions at 1.58 AGeV beam energy measured by HADES. Although, the High Acceptance DiElectron Spectrometer (HADES) at GSI was primarily designed to measure Di-Electrons, it also features a very rich program measuring hadronic probes in the region of moderate temperature and high-baryon density in the QCD phase...
