Resonances and Hypernuclei (II): Parallel 5
- Domenico Elia (INFN Bari)
The Λ binding energy difference, which is called the charge symmetry breaking in the ground states of a pair of A = 4 hypernuclei, $^{4}_{\Lambda}$H and $^{4}_{\Lambda}$He, was measured to be $\Delta B^{4}_{\Lambda}(0^{+}_{g.s.})$ ≈ 350 keV in nuclear emulsion experiments in 1970s. In the 2015 experiment from J-PARC, the binding energy difference in excited states $\Delta...
The $^{3}_{\Lambda}\text{H}$ is a bound state of proton (p), neutron (n) and $\Lambda$. Studying its characteristics provides insights about the strong interaction between the $\Lambda$ and ordinary nucleons. In particular, the $^{3}_{\Lambda}\text{H}$ is an extremely loosely bound object, with a large wave function. As a consequence, the measured (anti-)$^{3}_{\Lambda}\text{H}$ production...
We study the cluster and hypernuclei production in heavy-ion collisions from SIS to RHIC energies based on the n-body dynamical transport approach PHQMD (Parton-Hadron-Quantum-Molecular-Dynamics). In PHQMD clusters are formed dynamically due to the interactions between baryons described on a basis of Quantum Molecular Dynamics (QMD) which allows to propagate the n-body Wigner density and...
The study of hyperon-nucleon (Y-N) interactions is of great interest in recent years because of its relation to high-density matter systems. For example, the presence of hyperons inside neutron stars would soften the equation of state. Hypernuclei, bound states of nucleons and hyperons, serve as a probe to study the Y-N interaction.
In this talk, the lifetime of ${}^{3}_{\Lambda}$H and...
