“…We explored the energy and density dependence of the S -wavep-nucleus potential as well as the role of thepN P-wave interaction, and compared the predictions forp binding energies and widths with the phenomenological RMF approach [2]. ThepN amplitudes are strongly energy and density dependent, as was shown in Fig.…”

Abstract. We studied thep interactions with the nuclear medium within the 2009 version of the ParisNN potential model. We constructed thep-nucleus optical potential using the Paris S -and P-wavepN scattering amplitudes and treated their strong energy and density dependence self-consistently. We considered a phenomenological P-wave term as well. We calculatedp binding energies and widths of thep bound in various nuclei. The P-wave potential has very small effect on the calculatedp binding energies, however, it reduces the corresponding widths noticeably. Moreover, the S -wave potential based on the Paris amplitudes supplemented by a phenomenological P-wave term yields thep binding energies and widths in very good agreement with those obtained within the RMF model consistent withp-atom data.

“…In the dynamical calculations, thep polarizes the nuclear core, causing changes in the nuclear density distribution and nucleon single-particle energies. In our previous calculations ofp quasi-bound states within the RMF model [17] it was demonstrated that the nuclear core is significantly affected by the extra antiproton -the nuclear density in the central region reaches 2 − 3 times the saturation density. Since thep optical potential is density dependent, such increase in the density would result in a considerable increase of thep binding energies and widths.…”

“…In the K − -nucleus frame the momentum dependent term is no-longer zero and provides additional downward energy shift. The energy shift δ √ s = √ s − E th can be expanded in terms of binding and kinetic energies as follows [13]: 5) where B N = 8.5 MeV is the average binding energy per nucleon,ρ is the average nuclear density, ρ max is the maximal value of the nuclear density,…”

We report on our recent self-consistent calculations of K − -nuclear quasi-bound states using a K − single-nucleon optical potential derived from 6 different chiral meson-baryon coupled-channel interaction models. They yield quite diverse K − 1s binding energies and rather small K − decay widths. Next, we supplement the K − single-nucleon potential by a phenomenological K − multinucleon potential introduced recently to achieve good fits to kaonic atom data [1]. We demonstrate a decisive impact of the K − multinucleon interactions on the widths of K − -nuclear states. The resulting widths are considerably larger than the corresponding binding energies. The only two models accepted by the analysis of Ref.[1] even do not yield any kaonic nuclear bound state in many-body nuclear systems with mass number A ≤ 40.
