旋转SU的稳定性（3）Skyrmion
Stability of the rotating SU(3) Skyrmion
摘要：
用平均场方法研究了八重态、十重态和反十重态重子的SU（3）Skyrme孤子的轮廓函数。在这种方法中，轮廓函数受到空间旋转，风味旋转和风味对称性破缺的影响。对于每个多重态，孤子仅在参数空间的限制区域内是稳定的。当味对称性破缺较大时，反十重态的面积比八重态和十重态的面积窄。这些参数由重子质量谱决定，孤子的形变对质量有相当大的影响。
英文摘要：
The profile functions of the SU(3) Skyrme soliton are investigated for the octet, decuplet, and antidecuplet baryons by the mean field approach. In this approach, the profile functions are affected by the spatial rotation, the flavor rotation, and the flavor symmetry breaking. The solitons are stable only in the restricted areas of the parameter space for each multiplet. When the flavor symmetry breaking is large, the area for the antidecuplet is narrow compared to those for the octet and decuplet. The parameters are determined by the baryon mass spectrum, and the deformation of the soliton has sizable effects on the masses.
