| 摘要 | In a nonlinear chiral SU(3) framework, we investigate the quark condensate in the strange matter including N, Sigma, Xi, and Lambda, making use of chiral symmetry spontaneous breaking Lagrangian and mean-field approximation. The results show that the chiral symmetry is restored partially when the strange matter density increases and that <(π) over right arrow (2)> plays a very important role in the strange matter which may approach the constituents of the neutron stars. In addition, we can find that the strange matter density where the pi-condensate emerges leads to the ratio of the nucleon number to baryon number. |
