摘要: 利用Monte Carlo模拟方法,我们在53×30非对称格点上计算了β=4.3处SU(2)EXP作用量的胶球质量。计算结果表明:M(2+)≈M(0+)。同时,对于它们的激发态质量M的估算结果为:M(0+)/M(0+)=2.6±0.3,M(2+)/M(2+)=2.9±0.4。

Abstract: A Monce Carlo Calculation of SU (2) glueball masses on an 53×30 asymmetric lattice for β=4.3 is performed. The fine-grained data told us, within error 20%, M(2+)≈M(0+). The Higher excited states are also estimated. The results are M(0+)/M(0+)=2.6±0.3 and M(2+)/M(2+)=2.9±0.4.
