Recent progress on few-body hypernuclei

Few-body $\Lambda$ hypernuclei provide valuable information towards understanding strange matter. Recent experimental progress by the STAR Collaboration at the RHIC facility and by the ALICE Collaboration at the LHC has been matched by theoretical progress reviewed here: (i) lifetimes of the hypertriton $_{\Lambda}^3$H, $_{\Lambda}^3$n if particle-stable, $_{\Lambda}^4$H and $_{\Lambda}^4$He and their charge symmetry breaking, and (ii) the onset of $\Lambda\Lambda$ hypernuclear binding.
