Benchmarking $$\mathbf {\Lambda }$$NN three-body forces and first predictions for $$A=3-5$$ hypernuclei
Year: 2025
Type: article
Abstract: Explicit expressions for the leading chiral hyperon-nucleon-nucleon three-body forces have been derived by Petschauer et al (Phys Rev C93:014001, 2016). An important prerequisite for including these three-body forces in few- and many-body calculations is the accuracy and efficiency of their partial-wave decomposition. A careful benchmark of the $$\Lambda $$ Λ NN potential matrix elements, computed using two robust and efficient partial-wave decomposition methods, is presented. In addition, results of a first quantitative assessment for the contributions of $${\Lambda }$$ Λ NN forces to the separation energies in $$A=3-5$$ A = 3 - 5 hypernuclei are reported.
