In Au+Au collisions at $1.23 A$ $GeV$ incident energy all particles carrying strangeness are produced below their respective free nucleon-nucleon threshold. As a consequence, the production cross section is very sensitive to medium effects like momentum distributions, two- or multi-step collisions and modification of the in-medium spectral distribution of the produced states. For the first...

The presence of strangeness non-conservation process $K^0 \leftrightarrow \bar K^0$ during the hadronic stage of relativistic nucleus-nucleus collisions will be discussed, as a possible mechanism for the excessive sub-threshold production of double-strange hyperons observed recently by HADES collaboration. We explain, why such process could remain unnoticed in the spectra of neutral $K^0_s$...

We report on the production of (multi-)strange hadrons measured in proton-lead (p-Pb) collisions at $\sqrt{s_{NN}}=5.02$ TeV and lead-lead (Pb-Pb) collisions at $\sqrt{s_{NN}} = 2.76$ TeV by ALICE at the LHC. A systematic study of strangeness production is of fundamental importance for determining if particle yields are consistent with expectations for a system that has reached thermal...

We systematically compare an event-by-event transport+viscous hydrodynamics hybrid model to data from the RHIC beam energy scan using a general Bayesian method. We probe multiple model parameters characterizing the initial state as well as fundamental quark-gluon plasma properties, calibrate the model to optimally reproduce experimental data, and extract quantitative constraints for all...

Femtoscopy is a technique allowing measurements of the space-time characteristics of particle production using correlations arising from the effects of quantum statistics and final state interactions. In AA collisions, the measurements of pions, kaons, and protons can be employed to test the hydrodynamic evolution of the system. In this talk we present the ALICE results for all three particle...

The high collision energies reached at the LHC lead to significant production yields of light (anti-)(hyper-)nuclei in proton-proton, proton-lead and, in particular, lead-lead collisions. The excellent particle identification capabilities of the ALICE apparatus allow for the detection of these rarely produced particles. Furthermore, the good vertexing performance gives the possibility to...

In a pp collision, the production of quark-antiquark pairs along a
color flux tube
precedes the fragmentation of the tube. Because of
local conservation laws, the production of a strange quark-antiquark
pair will
lead to the correlation of adjacently produced
hadrons. Adjacently
produced hadrons can be signalled by their
rapidity difference
falling within the window of $|\Delta y...

The data on the $p_T$ spectra of $\phi$ and $\Omega$ at LHC can be replotted in a way that shows exponential behavior up to $p_T=6$ GeV/c with the same slope for both particles and for nearly all centralities. They are empirical properties without any theoretical input. Such behaviors for $\phi$ and $\Omega$ are intriguing because of the ambiguity of the origin of the underlying strange quarks...
