Old and New in Strangeness Nuclear Physics
arXiv:1811.00268 · doi:10.1063/1.5118369
The paper reviews ongoing issues in strangeness nuclear physics, focusing on hypernuclear lifetimes, charge‑symmetry breaking, overbinding of light hypernuclei, and the behavior of the Λ*(1405) in strange matter.
Abstract
Several persistent problems in strangeness nuclear physics are discussed in this opening talk at HYP2018, Portsmouth-Norfolk VA, June 2018: (i) the $^3_Î$H and $^3_Î$n (if existing) lifetimes; (ii) charge symmetry breaking in $Î$ hypernuclei; (iii) the overbinding of $^5_Î$He which might be related to the hyperon puzzle in neutron stars; and (iv) does $Î^\ast$(1405) survive in strange hadronic matter?
