Abstract

We carried out four-body calculations of ⁴_ΛH and ⁴_ΛHe taking both the 3N + Λ and 3N + Σ channels explicitly with the use of realistic N N and Y N interactions. The Σ-channel component plays an important role in binding energies of the A = 4 hypernuclei though the admixture is approximately 1%. The ΛN - ΣN coupling is found to be of central-force type in the Nijmegen model D and of tensor-force type in the model F.
