As an introduction to the “topical session on ΛNN three-body force” in HYP2022, a scenario to solve the hyperon puzzle and to elucidate high density matter in neutron stars is proposed. It is related to the J-PARC Hadron Facility extension project, in which experimental studies of ΛNN three-body force (3BF) via high precision spectroscopy of Λ hypernuclei and high quality ΛN scattering are one of the flagship subjects in the project. Development of theoretical methods to extract 3BF effects from experimental data and to reliably extrapolate them to higher density is challenging but extremely important.
