摘要:

本文研究了赝标胶球与标量场、赝标夸克-反夸克介子场以及与核子及其手征伙伴的相互作用。在这两种情况下,我们引入相应的手征拉格朗日量,并讨论其性质。我们计算了晶格模拟预测的质量约为2.6 GeV的赝标胶球的介子和重子衰变。

英文摘要:

We study the interactions of the pseudoscalar glueball with scalar and pseudoscalar quark-antiquark meson fields and with the nucleon and its chiral partner. In both cases we introduce the corresponding chiral Lagrangian and discuss its properties. We calculate the mesonic and baryonic decays of a pseudoscalar glueball with mass of about 2.6 GeV as predicted by Lattice simulations.
