| 摘 要： | 应用改进的格点哈密顿量和保持连续极限的耦合集团展开方法计算了2+1维SU(3)0+和0－胶球的质量.计算到三级近似,标度行为已经很好.与未改进的格点哈密顿量作的同样近似比较,改进的结果较快地进入标度区,而且标度性也较好.

| Abstract: | An improved lattice Hamiltonian is applied to the SU (3) lattice gauge theory in 2+1 dimensions. The glueball masses of 0 + and 0 have been calculated by using the coupled clusters expansion with the truncated eigenvalue equations in a scheme preserving the continuum limit. The calculations up to third order are carried out, and the results show better scaling behavior than that given by non-improved one. |
