We study the production of the doubly strange Ξ baryon in subthreshold p + A collisions using a BUU type transport model. We propose a new mechanism for Ξ creation in a two-step process via hyperon-nucleon collisions. We study the influence of the anisotropy of hyperon production in N + N collisions on the Ξ multiplicity. Applying reasonable assumptions on the unknown elementary cross sections, we are able to reconstruct the Ξ yield observed by the HADES collaboration (GSI, Darmstadt) in subthreshold p+Nb collisions.

Spallation is one of possible scenarios of proton - nucleus reaction considered nowadays. Pions are the most abundantly produced mesons during the reactions. Boltzmann-Uehling-Uhlenbeck (BUU) model was used to describe pion spectra, results will be presented.
