We study the baryon-baryon interactions with strangeness $S = -2$ and corresponding momentum correlation functions in leading order covariant chiral effective field theory. The relevant low energy constants are determined by fitting to the latest HAL QCD simulations, taking into account all the coupled channels. Extrapolating the so-obtained strong interactions to the physical point and...
The halo phenomenon is a hot topic in the nuclear structure study from both the theoretical and experimental points of view. Deep insights into the nucleon-nucleon interaction are needed to understand this phenomenon. Many neutron or proton-halo nuclei are observed in neutron or proton-rich nuclei by the experiments. With the strangeness quark included, the hyperon could influence the halo...
We study the charge symmetry breaking (CSB) effect in the binding energy of mirror
hypernuclei in the mass region $A=7\sim 48$ in relativistic mean field (RMF) models introducing $NN$ and $\Lambda N$ interactions. The phenomenological $\Lambda N$ CSB interaction is introduced and the strength parameter is fitted to reproduce the experimental binding energy difference between the mirror...
