Hyperon haloes in Lambda hypernuclei in the relativistic continuum Hartree-Bogoliubov theory

We investigate the existence of a single-A hyperon halo in C-15(3A) and a two-A hyperon halo in C-16(4A). Ground-state properties of hyperon carbon isotopes, such as density distributions, single particle levels in the canonical basis, the binding energy, A separation energy and radii, are calculated and discussed by using the relativistic continuum Hartree-Bogoliubov theory. The hyperon halo phenomenon in C-15(3A) and C-16(4A) is supported by the discussion of the weakly bound state 1p(3/2), extended density distribution and small separation energy of the A hyperon.Physics, MultidisciplinarySCI(E)中国科学引文数据库(CSCD)15ARTICLE121775-17781
