Description

The study of hypernuclei in relativistic ion collisions open new
opportunities for nuclear and particle physics. The main processes
leading to the production of hypernuclei in these reactions are
(1) the disintegration of large excited hyper-residues (target-
and projectile-like), and (2) the coalescence of hyperons with other
baryons into light clusters. We use the transport, coalescence and
statistical models to describe the whole process, and demonstrate
the advantages over the traditional hypernuclear methods: A broad
distribution of predicted hypernuclei in masses and isospin
allows for investigating properties of exotic hypernuclei, as well
as the hypermatter both at high and low temperatures.
We point at the abundant production of multi-strange nuclei and new
bound/unbound hypernuclear states. The realistic estimates of
hypernuclei yields in various collisions are presented [1].
Other processes well known in normal reactions: evaporation,
fission, multifragmentation break-up are calculated in the case of
hypermatter [2]. There is a saturation of the hypernuclei production
at high energies [1], therefore, the optimal way to pursue this
experimental research is to use the accelerator facilities of
intermediate energies, like FAIR (Darmstadt) and NICA (Dubna).
