Statistical double hypernuclear formation from absorption at rest in light nuclei
Akira Ohnishi, Chikako Ishizuka, Kohsuke Tsubakihara +1
We investigate double hyperfragment formation from the statistical decay of double compound nuclei produced in the absorption at rest in light nuclei, $^{12}\mathrm{C…
Isovector potential of in nuclei and neutron star matter
K. Tsubakihara, A. Ohnishi, T. Harada
We determine the coupling constants of hyperon with mesons in relativistic mean field (RMF) models using atomic shift data and examine the effects of on the neutron s…
Three-body couplings in RMF and its effects on hyperonic star equation of state
Kohsuke Tsubakihara, Akira Ohnishi
We develop a new relativistic mean field (RMF) model including explicit three-body couplings and apply it to hyperonic systems and neutron star matter. The recent observation of th…
Nuclear Matter and Finite Nuclei in the Effective Chiral Model
P. K. Sahu, K. Tsubakihara, A. Ohnishi
We systematically investigate the vacuum stability and nuclear properties in the effective chiral model with higher order terms in . We evaluate the model parameters by consider…
Lambda hypernuclei and neutron star matter in a chiral SU(3) relativistic mean field model with a logarithmic potential
K. Tsubakihara, H. Maekawa, H. Matsumiya +1
We develop a chiral SU(3) symmetric relativistic mean field (RMF) model with a logarithmic potential of scalar condensates. Experimental and empirical data of symmetric nuclear mat…
Tables of Hyperonic Matter Equation of State for Core-Collapse Supernovae
C. Ishizuka, A. Ohnishi, K. Tsubakihara +2
We present sets of equation of state (EOS) of nuclear matter including hyperons using an SU_f(3) extended relativistic mean field (RMF) model with a wide coverage of density, tempe…
