Calculations of p̄-nuclear states within the Paris N̄N potential model

Abstract

We performed calculations of p̄-nuclear quasi-bound states using an optical potential derived from the 2009 version of the Paris N̄N potential model. Self-consistent treatment of strong energy dependence of the considered S- and P-wave p̄N scattering amplitudes is essential for proper evaluation of p̄ binding energies and widths. The P-wave potential has very small effect on the calculated p̄ binding energies, however, it reduces the corresponding widths in large measure. The Paris S-wave potential supplemented by a phenomenological P-wave term yields the p̄ binding energies and widths very close to those obtained within the RMF model consistent with p̄-atom data.
