Possible lightest $Ξ$ Hypernucleus with Modern $Ξ N$ Interactions

E. Hiyama, K. Sasaki, T. Miyamoto +4

Experimental evidence exists that the $Ξ$ -nucleus interaction is attractive. We search for $N N Ξ$ and $N N N Ξ$ bound systems on the basis of the AV8 $N N$ potential combined with eithe…

Equation of state for neutron stars with hyperons by the variational method

H. Togashi, E. Hiyama, Y. Yamamoto +1

We investigate the effects of the odd-state part of bare $ΛΛ$ interactions on the structure of neutron stars (NSs) by constructing equations of state (EOSs) for uniform nuclear mat…

Four-body structure of $_{Λ}^{7}$ Li and $Λ N$ spin-dependent interaction

E. Hiyama, Y. Yamamoto, Th. A. Rijken +1

Two spin-doublet states of % $3/ 2^{+}$ - $1/ 2^{+}$ and $7/ 2^{+}$ - $5/ 2^{+}$ in $_{Λ}^{7}$ Li are studied on the basis of the $α + Λ + n + p$ four-body model. We employ the two-body interactions which rep…
