Status of the hyperon-nucleon interaction in chiral effective field theory

The Jülich-Bonn group aims at an extensive study of the baryon-baryon ($BB$) interaction involving strange baryons ($\mathrm{\Lambda }$, $\mathrm{\Sigma }$, $\mathrm{\Xi }$) within SU(3) chiral effective field theory. An overview of achievements and new developments over the past few years is provided. The topics covered are: 1) Derivation of the leading charge-symmetry breaking (CSB) interaction for the $\mathrm{\Lambda }N$ system and its application in a study of CSB effects in $A$=$4$ $\mathrm{\Lambda }$-hypernuclei. 2) Updated results for the $\mathrm{\Xi }N$ interaction at NLO and predictions for ${\mathrm{\Xi }}^{-}p$ correlation functions. 3) Extension of the $\mathrm{\Lambda }N$-$\mathrm{\Sigma }N$ interaction to next-to-next-to-leading order.
