Abstract

Variational calculations for s-shell hypernuclei are performed by explicitly including Σ degrees of freedom. Four sets of YN interactions [SC97d(S), SC97e(S), SC97f(S), and SC89(S)] are used. The bound-state solution of HΛ5e is obtained and a large energy expectation value of the tensor ΛNΣN transition part is found. The internal energy of the H4e subsystem is strongly affected by the presence of a Λ particle with the strong tensor ΛNΣN transition potential.
