A minimally constructed Λ-nucleus density-dependent optical potential is used to calculate binding energies of observed 1sΛ, 1pΛ states across the periodic table, leading to a repulsive ΛNN contribution D(3)Λ≈14 MeV to the phenomenological Λ-nucleus potential depth DΛ ≈ −30 MeV. This value is significant in connection with the so-called ’hyperon puzzle.’
