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

The J\"ulich-Bonn group aims at an extensive study of the baryon-baryon ($BB$) interaction involving strange baryons ($\Lambda$, $\Sigma$, $\Xi$) 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 $\Lambda N$ system and its application in a study of CSB effects in $A$=$4$ $\Lambda$-hypernuclei. 2) Updated results for the $\Xi N$ interaction at NLO and predictions for $\Xi^- p$ correlation functions. 3) Extension of the $\Lambda N$-$\Sigma N$ interaction to next-to-next-to-leading order.
