Old and New in Strangeness Nuclear Physics

Abstract

Several persistent problems in strangeness nuclear physics are discussed in this opening talk at HYP2018, Portsmouth-Norfolk VA, June 2018: (i) the ${}_{\Lambda }^3$H and ${}_{\Lambda }^3$n (if existing) lifetimes; (ii) charge symmetry breaking in $\Lambda$ hypernuclei; (iii) the overbinding of ${}_{\Lambda }^5$He which might be related to the hyperon puzzle in neutron stars; and (iv) does ${\Lambda }^{\ast }$(1405) survive in strange hadronic matter?

12 pages, 7 figures, 3 tables; v2--updated ${}_{\Lambda }^3$H lifetime calculation results [48] in Table 3; v3--updated references, matching published version
