$\hat{I}›NN$ content of $\hat{I}›$-nucleus potential

Abstract

A minimally constructed $\hat{I}›$-nucleus density-dependent optical potential is used to calculate binding energies of observed $1s_{\hat{I}}›$, $1p_{\hat{I}}›$ states across the periodic table, leading to a repulsive $\hat{I}›NN$ contribution $D_{\hat{I}}{›}^{(3)}\approx 14$ MeV to the phenomenological $\hat{I}›$-nucleus potential depth $D_{\hat{I}}›\approx -30$ MeV. This value is significant in connection with the so-called 'hyperon puzzle'.
