Abstract:

Antiproton-induced reactions on nuclei at the beam energies from hundreds MeV up to several GeV provide
an excellent opportunity to study interactions between the antiproton and secondary particles (mesons, baryons
and antibaryons) with nucleons. The antiproton projectile is unique in the sense that most of the annihilation
particles are relatively slow in the target nucleus frame. Hence, the prehadronic e ects do not much influence
their interactions with the nucleons of the nuclear residue. Moreover, the particles with momenta less than
about 1 GeV/c are sensitive to nuclear mean field potentials. This paper discusses the microscopic transport
calculations of the antiproton-nucleus reactions and is focused on three related problems: (i) antiproton potential
determination, (ii) possible formation of strongly bound antiproton-nucleus systems, and (iii) strangeness
production.
