Baryon-baryon interaction from chiral effective field theory

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. (author)
