[en] The present state of knowledge on hypernuclei is outlined briefly: their creation, detection, role and possible existence on hyperdense celestial bodies, the Λ-nucleon interaction

[en] Several sessions of the Working Group on Hadronic and Nuclear Spectroscopy dealt with different aspects of strange particle nuclear physics, including hyper-nuclear spectroscopy, strange dibaryons, and K⁺ interactions with nuclei. Recent developments in this area are summarized here, and open questions are identified. Some prospects for optimum use of existing facilities, as well as the desired characteristics of future ones, are discussed

[en] A statistical combination of the experimental lifetime estimations available in the literatures is performed for ³_ΛH and ⁴_ΛH, including several recent measurements. The combined average values of the lifetime for ³_ΛH and ⁴_ΛH are respectively 216₋₁₆⁺¹⁹ ps and 192₋₁₈⁺²⁰ ps with a reduced χ² of 0.89 and 0.48. A new insight into the lifetime estimation of the HypHI Phase 0 experiment by a Bayesian approach is also presented. In this approach, several different prior distributions including the combination of previous lifetime data and a Jeffrey prior are used. The principal mode and the smallest credible interval at 68% of the posterior distribution, given by the prior belief of the previous measurements, are 217₋₁₆⁺¹⁹ ps and 194₋₁₈⁺²⁰ ps respectively for ³_ΛH and ⁴_ΛH. The two employed approaches have revealed that the lifetime of hypernuclei ³_ΛH and ⁴_ΛH can be shorter than the Λ–hyperon lifetime

[en] The physics of the weak decay of hypernuclei is briefly reviewed from a theoretical point of view. Special regard is devoted to the recent progress concerning the determination of the non-mesonic decay widths and the asymmetry parameters. Convincing evidence has been achieved for a solution of the long-standing puzzle on the ratio Γ_n/Γ_p. Very recently, it has been shown that the exchange of a ππ pair in the weak mechanism plays a crucial role in explaining the discrepancies between theory and experiment on the decay asymmetries
