Beyond mean-field approach for pear-shaped hypernuclei
H. J. Xia, X. Y. Wu, H. Mei +1
We develop both relativistic mean field and beyond approaches for hypernuclei with possible quadrupole-octupole deformation or pear-like shapes based on relativistic point-coupling…

J. M. Yao, H. Mei, K. Hagino +1
We report the recent progress in relativistic mean-field (RMF) and beyond approaches for the low-energy structure of deformed hypernuclei. We show that the hyperon with orbital…
Disappearance of nuclear deformation in hypernuclei: a perspective from a beyond-mean-field study
H. Mei, K. Hagino, J. M. Yao +1
The previous mean-field calculation [Myaing Thi Win and K. Hagino, Phys. Rev. C{\bf 78}, 054311 (2008)] has shown that the oblate deformation in Si disappears when a $…

X. Y. Wu, H. Mei, J. M. Yao +1
[Background] The hyperon impurity effect in nuclei has been extensively studied in different mean-field models. Recently, there is a controversy about whether the hyperon is mo…

H. Mei, K. Hagino, J. M. Yao
We apply the generator coordinate method (GCM) to single- hypernuclei in order to discuss the spectra of hypernuclear low-lying states. To this end, we use the same relativistic…

W. X. Xue, J. M. Yao, K. Hagino +3
The impurity effect of hyperon on atomic nuclei has received a renewed interest in nuclear physics since the first experimental observation of appreciable reduction of transit…
