Measurements of strange hadron production provide information on the properties of strongly interacting matter and on the mechanisms of particle production in high-energy collisions. The NA61/SHINE experiment at the CERN SPS North Area investigates these processes through a two-dimensional scan in collision energy and system size, covering a wide range of hadronic and nuclear interactions.

Hyperons are an important probe of strangeness production and the properties of strongly interacting matter in relativistic heavy-ion collisions. While Λ and multi-strange hyperons have been measured extensively, the Σ⁰ hyperon remains much less explored. This is particularly interesting since Σ⁰ shares the same quark content as Λ but carries different isospin, so the Σ⁰/Λ ratio can provide...
There has been a significant debate about the mass of sexaquark, a highly bound compact six quark state which has been hypothesised as a candidate for dark matter. Here we present a simplistic approach motivated by the formalism of Cooper Triples in condensed matter physics to provide a range for the mass which is consistent with the previous bounds. We also discuss the temperature and...
Heavy quarks are produced in hard partonic scatterings at the very early stage of heavy-ion collisions and they experience the whole evolution of the Quark-Gluon Plasma medium. Femtoscopic correlations, i.e. two-particle correlations at low relative momentum, are sensitive to the final-state interactions as well as to the extent of the region from which the correlated particles are emitted. A...
The condition to preserve the internal symmetry of the system leads to new constraints for the kinetic equations.
Abelian symmetries lead to extensive variables that scale proportionally with the system size or number of particles. Nonabelian symmetries lead to variables that do not scale proportionally with the system size or number of particles and are realized by higher factorial...
Fluid-dynamical modeling of heavy-ion collisions at RHIC BES energies is complicated by primary collisions and collective expansion taking place simultaneously. In a multi-fluid model this problem is circumvented by describing the colliding nuclei and produced particles as three separate fluids. I describe the present status of our multi-fluid model MUFFIN (MUlti Fluid simulation of Fast IoN...
