Remarks on the s-shell Λ-hypernuclei
Description
The complexities of the s-shell Λ-hypernuclei (A less than or equal to 5) are explored. Difficulties associated with attempts to describe the hyperon-nucleon (YN) interaction in all such Λ-hypernuclei by simple, effective Λp and Λn potentials are examined. The explicit A dependence of the effective YN interaction due to ΛN-ΣN coupling and isospin differences among the nuclear core states is investigated. The necessity of using exact four-body theory to calculate small charge-symmetry-breaking effects (in the A = 4 system) using ΛN potentials fitted to free ΛN scattering data is emphasized. Possible use of s-shell hypernuclear binding energies to help distinguish among candidate YN potential parameterizations is discussed
