Λ Nuclear physics

Abstract

We examine briefly whether our realistic models of nuclear forces, which govern the interactions of neutrons and protons with one another and form the basis for precision calculations describing conventional few-nucleon systems, can extrapolate beyond the realm of S = 0 nuclear physics where they were developed, or whether they are merely exquisite interpolation tools within the bounds of well established neutron-proton physics. To address that issue, we examine certain novel aspects of Λ hypernuclei, exploring how few-body hypernuclei provide a laboratory in which one can investigate properties of the ΛN interaction. Finally we look forward to possible future experiments that can enhance our minimal data base for hyperon-nucleon scattering and reactions.
