摘要
利用Monte Carlo模拟方法,我们在5~3×30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。
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.
