本文给出了在考虑动力学费米子效应的情况下,用赝费米子方法对43·24格点进行格点QCD模拟得到的0++和2++胶球质量的第一个结果.质量由伴随线相关函数的指数衰减确定。我们发现M2++<M0++,将贝格,比卢瓦尔和沃温克尔关于纯规范情形的一个结果推广到全理论.
We present first results for the masses of the 0++and 2++glueballs obtained from a simulation of lattice QCD on a 43·24 lattice with the effects of dynamical fermions included using the pseudo-fermion method. The masses are determined from the exponential falloff of adjoint line correlation functions. We find that M2++<M0++, extending an earlier result by Berg, Billoire and Vohwinkel for the pure gauge case to the full theory.
