格点上的QCD单极与规范不变性

QCD Monopoles on the Lattice and Gauge Invariance

Adriano Di Giacomo

摘要:

长期存在的问题是解决为什么在格子配置中观察到的单极子的数量和位置取决于用于检测它们的规范的选择,而不是明显的要求,即单极子作为物理对象,必须具有规范不变的状态。它被证明,通过使用非阿贝尔比安奇身份,单极子确实是规范不变的:用于检测它们的技术,而不是一个效率取决于阿贝尔投影的选择,在一个已知的和可控的方式。

英文摘要:

The long standing problem is solved why the number and the location of monopoles observed in Lattice configurations depend on the choice of the gauge used to detect them, in contrast to the obvious requirement that monopoles, as physical objects, must have a gauge-invariant status. It is proved, by use of non-abelian Bianchi identities, that monopoles are indeed gauge-invariant: the technique used to detect them has instead an efficiency which depends on the choice of the abelian projection, in a known and controllable way.
