Abstract
To sustain a neutron star with about two times the solar mass, multibaryons including hyperons are expected to produce repulsive effects in the interior of its high-baryon-density region. To examine possible quark-Pauli repulsion among the baryons, we solve the eigenvalue problem of the quark antisymmetrizer for three octet-baryons that are described by most compact spatial configurations. We find that the Pauli blocking effect is weak in the system, while it is strong in the system. The appearance of the hyperon is suppressed in the neutron star interior but no quark-Pauli repulsion effectively works for the hyperon.
