我们简要地讨论了将伪标量胶球插值算符纳入计算ETA和etaprime介子质量的变分基中的一些问题。作为开始，我们给出了在nf=2+1+1扭曲质量规组态上的赝标胶球算符相关器的一些初步结果。给出了开边界条件对淬火QCD中三个胶球质量影响的初步结果。简要讨论了胶球相关器的统计特性。
We briefly discuss some issues concerning including the pseudoscalar glueball interpolating operators into the variational basis for computing the masses of the eta and etaprime mesons. As a start we present some preliminary results for the correlators from pseudoscalar glueball operators on nf = 2+1+1 twisted mass gauge configurations. Preliminary results for the effect of open boundary conditions on the masses of three glueballs computed in quenched QCD are presented. The statistics of glueball correlators are briefly discussed.
