Abstract
We report on the results on the dynamical modelling of cluster formation with the new combined PHSD+FRIGA model at Nuclotron and NICA energies. The FRIGA clusterisation algorithm, which can be applied to the transport models, is based on the simulated annealing technique to obtain the most bound configuration of fragments and nucleons. The PHSD+FRIGA model is able to predict isotope yields as well as hyper-nucleus production. Based on present predictions of the combined model we study the possibility to detect such clusters and hypernuclei in the BM@N and MPD/NICA detectors.
Highlights
Heavy-ion collisions provide the unique possibility to create and investigate hot and dense matter in the laboratory
The capture of the produced hyperons by clusters of nucleons leads to the hypernuclei formation which is a very rare process at strangeness threshold energies
It is important to have the robust modelling of hypernuclei and cluster formation in order to study the detector replica and to have the possibility to optimize the experimental setup for the best efficiency
Summary
Heavy-ion collisions provide the unique possibility to create and investigate hot and dense matter in the laboratory. The MST clusters and individual particles are recombined in all possible ways into fragments or left as single nucleons, such as to choose that configuration which has the highest binding energy [5]. This procedure is repeated many times (within a Metropolis procedure) and it automatically leads to the most bound configuration. There, the approach predicts a stabilization in the hadron and fragment yields around 15 fm/c This earlier clusterization time as been chosen in the following for studying various fragments observables. We observe there that the model reproduces well the experimental data
