We discuss strangeness production in heavy-ion collisions within and around the energy range of the planned NICA facility. We describe the minimal statistical model, in which the total strangeness yield is fixed by the observed or calculated K + multiplicity. We show how the exact strangeness conservation can be taken into account on the event-by-event basis in such a model. We argue that from strange particle yields one can reveal information about the collision dynamics and about possible modifications of particle properties in medium. This can be best achieved if the complete strangeness measurement is performed, i.e. kaons, anti-kaons, hyperons and multistrange hyperons are registered in the same experimental setup. In particular the production of hadrons containing two and more strange quarks, like Ξ and Ω baryons could be of interest.

“…This effect is expected to enhance the polymerization rates up to surpassing certain point (%1.8 to 2.5 wt%) wherein the lower rates of insertion of the ethylene comonomer decrease the yields. [34][35][36] Figure 4 illustrates the molecular weights obtained along the series with the three metallocenes. The first important finding from this figure is that metallocene B gave rise always to the lower molecular weights, regardless of the amount of ethylene loaded.…”

The synthesis in a liquid propene phase of ethylene–propylene copolymers of low molecular weights (3 000–20 000 g mol−1) is accomplished using three different metallocenes containing bridged bis(indenyl) moieties: (A) rac‐dimethylsilylbis(4,5,6,7‐tetrahydro‐1‐indenyl)zirconium dichloride, (B) rac‐ethylenebis(4,5,6,7‐tetrahydro‐1‐indenyl)zirconium dichloride, and (C) rac‐ethylenebis(indenyl)zirconium dichloride. Hydrogen pressures higher than 1 bar were required to drop the molecular weight below 25 000 g mol−1. Metallocene B gives rise to the copolymers with lower molecular weights (<5 000 g mol−1), irrespective of the ethylene content, due to the presence of a hydrogenated six membered ring in the indenyl moiety as well as a CH2 bridge. DSC experiments indicate that for low ethylene contents (below 4 wt%), metallocene A gives rise to copolymers with the highest melting temperatures and the lowest melting enthalpies, suggesting the existence of longer isotactic propylene sequences into the copolymer backbone.

“…Relativistic nucleus-nucleus (A+A) collisions have been studied so far at beam energies from 0.1 to 2 A GeV at the SIS (Schwerionen synchrotron), from 2 to 11.6 A GeV at the AGS (alternating gradient synchrotron) and from 20 to 160 A GeV at the SPS [13,14]. While [24,25] is depicted for different bombarding energies.…”

Abstract. Particle number fluctuations and correlations in nucleus-nucleus collisions at SPS and RHIC energies are studied within microscopic transport approaches. In this review we focus on the Hadron-String-Dynamics (HSD) and Ultra-relativisticQuantum-Molecular-Dynamics (UrQMD) models The obtained results are compared with the available experimental data as well as with the statistical models and the model of independent sources. In particular the role of the experimental centrality selection and acceptance is discussed in detail for a variety of experimental fluctuations and correlation observables with the aim to extract information on the critical point in the (T, µ B ) plane of strongly interacting matter.
