Abstract: Recent results from the ongoing study of the baryon–baryon interaction within chiral effective field theory (EFT) by the Jülich–Bonn–Munich Group are reported. Specifically, a calculation of the in-medium properties of a hyperon–nucleon (YN) interaction derived within chiral EFT and fitted to ΛN and ΣN scattering data is reviewed. Furthermore, the relevance of three-body forces for hypernuclei is addressed and potentials for the leading order three-baryon interactions are discussed, which involve contact terms and irreducible one- and two-meson exchange diagrams. Finally, first results for baryon–baryon scattering in the strangeness S = −2 sector, obtained in chiral EFT up to NLO, are presented.
