Abstract

On the basis of a dynamical Relativistic Mean Field (RMF) model we study the response of a nucleus on an antiproton implanted in its interior. We solve the Vlasov equation for the p̄-nuclear system assuming different strengths of attractive p̄ potential and show that a compressed state is formed on a rather short time scale of about 4 ÷ 10 fm/c. The evolution of the system after p̄ annihilation is simulated using the Giessen Boltzmann-Uehling-Uhlenbeck (GiBUU) transport model. Finally, several observables sensitive to the p̄ annihilation in a compressed nuclear configuration are proposed, e.g. the nucleon kinetic energy spectra and the total invariant mass distributions of produced mesons.
