摘要:

本文介绍了基于复群的量子色动力学的研究。我们的目的是表明,一个规范理论与复杂的对称性发展的一些功能所需的描述的一个限制相。这一理论导致胶子的传播特性的i粒子,传播的基本组成部分,在格里波夫的情况下,连同胶子传播的模式预测的特胡夫特的夸克禁闭。通过这种方式,我们在同一理论中提出了一种可能的胶子凝聚,以及与费米子耦合后的限制夸克间势。这是一个新奇的现象,因为到目前为止,所有的GZ类理论都不产生夸克禁闭。

英文摘要:

We introduced here the study of a QCD based on a complex group. Our aim is to show that a gauge theory with a complex symmetry develops some of the features required for the description of a confined phase. This theory leads to gluons with propagations characteristic of i-particles, fundamental constituents of propagators in the Gribov scenario, together with a gluon propagating with the mode predicted by 't Hooft for the quark confinement. In this way, we present in this same theory a possible gluon condensate, together with a confining interquark potential after the coupling to fermions. This is a novelty, as, up to now, all theories of the GZ kind do not generate quark confinement.
