Interaction of antiprotons with nuclei

Original language description

We performed fully self-consistent calculations of (p) over bar -nuclear bound states using a complex (p) over bar -nucleus potential accounting for (p) over bar -atom data. While the real part of the potential is constructed within the relativistic mean-field (RMF) model, the (p) over bar annihilation in the nuclear medium is described by a phenomenological optical potential. We confirm large polarization effects of the nuclear core caused by the presence of the antiproton. The (p) over bar annihilation is treated dynamically, taking into account explicitly the reduced phase space for annihilation from deeply bound states as well as the compressed nuclear density due to the antiproton. The energy available for the products of (p) over bar annihilation in the nuclear medium is evaluated self-consistently, considering the additional energy shift due to transformation from the (p) over barN system to (p) over bar -nucleus system. Corresponding (p) over bar widths in the medium are significantly suppressed, however, they still remain considerable for the (p) over bar potential consistent with experimental data.
