QCD中单极凝聚的维数变化

Dimensional Transmutation by Monopole Condensation in QCD

Y. M. Cho

摘要:

我们比较了QCD中两种相互竞争的色禁闭结构,即量子凝聚和阿贝尔占优,并指出量子凝聚是产生色禁闭的原因。为了证明这一点,我们提出了一个新的单圈QCD有效作用量的规范不变积分表达式,该表达式没有红外发散。由此我们证明,正如GSO投影恢复了NSR弦论中的超对称性和模不变性一样,色反射不变性(“C投影”)保证了规范不变性和超对称凝聚的稳定性。这在QCD中确立了量子力学的优势。在这样做的时候,我们指出的Savvidy-Nielsen-Olesen(SNO)的有效行动的计算中的关键缺陷。

英文摘要:

We compare two competing conjectures of the color confinement in QCD, the monopole condensation and the Abelian dominance, and show that it is the monopole condensation which is responsible for the confinement. To demonstrate this we present a new gauge invariant integral expression of the one-loop QCD effective action which has no infra-red divergence. With this we show that, just as the GSO-projection restores the supersymmetry and modular invariance in NSR string theory, the color reflection invariance ("the C-projection") assures the gauge invariance and the stability of the monopole condensation. This establishes the monopole dominance in QCD. In doing so we point out critical defects in the calculation of the Savvidy-Nielsen-Olesen (SNO) effective action.
