Query: The decays $\Xi_b \to \Lambda_b \, \pi$ and diquark correlations in
  hyperons   The decays $\Xi_b \to \Lambda_b \pi$ are strangeness changing weak
transitions involving only the light diquark in the baryon. Thus these decays
can test the properties of such diquarks, in particular the suggestions
existing in the literature of enhanced correlations in $J^P=0^+$ light
diquarks. We revisit the estimates of the rates of these decays and point out
that with the enhanced correlation their branching fraction can reach a few
percent and may become visible in the measurements of differences of the
lifetimes of $b$ baryons.
