标量胶球模型中的质量间隙

Mass gap in scalar glueball model

Vladimir Dzhunushaliev

摘要:

在胶子凝聚的非微扰标量模型的基础上,讨论了胶子球模型。两个标量场分别描述了属于一个子群$SU(2) \subset SU(3)$和一个陪集$SU(3) / SU(2)$的规范势分量的量子涨落。在这种情况下,出现了非微扰量子修正。这些修正与强相互作用规范场算符的隐结构有关。得到了两个标量场的正则解。该解是一个充满SU(3)规范场量子涨落的球。给出了规范势量子涨落色散的空间分布。

英文摘要:

On the basis of a nonperturbative scalar model of gluon condensate the model of glueball is considered. Two scalar fields describe quantum fluctuations of gauge potential components belonging to a small subgroup $SU(2) \subset SU(3)$ and a coset $SU(3) / SU(2)$ correspondingly. In this consideration nonperturbative quantum corrections appear. The corrections are connected with a hidden structure of operators of strongly interacting gauge field. A regular solution for two scalar fields is obtained. The solution is a ball filled with quantum fluctuations of SU(3) gauge field. The space distribution of the dispersion of quantum fluctuations of gauge potential is presented.
