Web25 sep. 2024 · Recent progress on hypernuclei. Avraham Gal. Some of last year's progress made in hypernuclear physics is reviewed as follows: (i) resolving the He overbinding problem in single- hypernuclei [1]; (ii) arguing that the onset of binding double- hypernuclei is most likely at =5, with the neutral systems n and n unbound by a large margin [2]; and ...

Web25 apr. 2024 · We study the energy spectra of Ξ hypernuclei C Ξ 15 and Be Ξ 12 with a relativistic mean field (RMF) model with meson exchange Ξ N interactions. The RMF parameters are optimized to reproduce the average energy of KINKA and IRRAWADDY events for the ground state and also the average energy of KISO and IBUKI events for … Webels used in studies of hypernuclei extend from nonrelativistic approaches based on OBE models for Λ-N interaction, to the relativistic mean field approximation and quark-meson coupling models. However, our knowledge of the Λ-nucleus in-teraction, and of hypernuclear systems in general, is restricted to the valley of β-stability.

High-energy heavy-ion collisions offer a unique way to study the behaviour of nuclear matter under conditions of extreme energy and density. One of the remarkable features of the particle production at high energies is the nearly equal abundance of matter and antimatter in the central rapidity region.
