Description
The study of hypernuclei in deep-inelastic relativistic collisions of
ion and other particle with nuclei open new opportunities for
nuclear/particle physics and astrophysics. We review the main processes
leading to the production of hypernuclei in these reactions: These are
the disintegration of large excited hyper-residues (target- and
projectile-like remnants with captured hyperons), and 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. Many processes well known in normal
reactions, such as evaporation, fission, multifragmentation, and
Fermi-break-up are generalized and calculated for the case of excited
hypermatter. There is a saturation of the hypernuclei production at
high energies, therefore, the optimal way to pursue this experimental
research is to use the accelerator facilities of intermediate energies.
