We consider the experimental data on yields of protons, strange $\Lambda$’s, and multistrange baryons ($\Xi$, $\Omega$), and antibaryons production on nuclear targets, and the experimental ratios of multistrange to strange antibaryon production, at the energy region from SPS up to LHC, and compare them to the results of the Quark-Gluon String Model calculations. In the case of heavy nucleus...

57. Probing partonic collectivity in large and small collision systems with strange hadrons in ALICEZuzana Moravcova (University of Copenhagen (DK))29/06/2022, 17:00talk
Measurements of anisotropic flow can be used to study transport properties and the evolution of the quark-gluon plasma (QGP), the hot and dense medium produced in heavy-ion collisions that expands collectively. In recent years, several similar features have been observed in high-multiplicity collisions of small systems, such as pp or p--Pb. However, it is still under debate whether the origin...

NA61/SHINE is a multi-purpose fixed-target experiment located at the H2 beamline of the CERN North Area. One of the main goals of the experiment is to study the phase transition and search for the critical point of the strongly interacting matter. Strangeness production is a long-known valuable probe for understanding particle production in high-energy physics due to the absence of strange...

The study of the strong interaction among stable and unstable hadrons is a fundamental question in nuclear physics and it is a key ingredient for the determination of the Equation of State of dense stellar objects, such as neutron stars. Two-particle correlation measurements are a prominent tool to probe the strong interaction with high precision even in the multi-strangeness sector, where...

The overall scanning method of the entire volume of the nuclear emulsion irradiated in the E07 experiment at J-PARC can provide to discover events that were not observed by the already-completed analyses with the emulsion-counter-hybrid method. Therefore, further analysis with the overall scanning technique can be used to observe a large number of single-$\Lambda$ hypernuclei, however, it...

Very recently, from January till March in 2022, the WASA-FRS HypHI experiment was performed at GSI for measuring the lifetime of the hypertriton and the ${}^{4}_{\Lambda}\mathrm{H}$ hypernucleus precisely as well as for confirming whether or not the $nn\Lambda$ bound state can exist. The experiment has been carried out with the WASA central detector with a complex of additional dedicated...

The distribution of neutrons with respect to protons in heavy nuclei is strongly related to isospin dependence of the nuclear equation of state. There exist several experimental methods to determine the neutron skin thickness in these nuclei: scattering of hadronic probes like $\pi$, p, and $\alpha$ particles on nuclei, antiproton-nucleus scattering or absorption, the electromagnetic dipole...

The production of hyperons serves as a tool to investigate the strong interaction in the non-perturbative energy regime. While there are several experimental results for $\Lambda$ hyperons in p+p reactions, measurements of the $\Sigma^{0}$ production are scarce. This talk presents a study of the $\Sigma^{0}$ production mechanism via the exclusive reaction $pp \to pK^{+}\Sigma^{0}$ at a beam...
