Production of strange particles and hypernuclei in spallation reactions from the coupling of intranuclear cascade and de-excitation models
Résumé
Motivated by a renewed interest in hypernucleus studies, the strangeness degree
of freedom was implemented in the intranuclear cascade model INCL. This model
takes care of the first stage of reactions between a nucleon (or a light
cluster) and a nucleus at energies from a few tens of MeV up to a few GeV. After
emission of fast particles, a hot remnant nucleus is produced and another model,
combined to INCL, handles the de-excitation (the ABLA model in our case). The
main ingredients will be discussed and results will be compared to experimental
data. The experimental kaon spectra for different target elements and at
different energies agree reasonable well with the model predictions. The main
remaining discrepancies are analysed and will be explained.
