Abstract

Selected light hypernuclei are studied using an α cluster model approach (the Hyper-THSR wave function) in combination with a density-dependent Λ hyperon-nuclear interaction derived from chiral SU(3) effective field theory. This interaction includes important two-pion exchange processes involving ∑N intermediate states and associated three-body mechanisms as well as effective mass and surface terms arising in a derivative expansion of the in-medium Λ selfenergy. Applications and calculated results are presented and discussed for 13 Λ C and 9 ΛBe. The lightest α clustered hypernucleus, 5 ΛHe, is also discussed in this context
