夸克禁闭的动力学机制

A dynamical mechanism for quark confinement

Kai Schwenzer

摘要:

近年来,对朗道规范QCD禁闭机制的理解有了新的进展。新兴的动力学描述的基础规范依赖的自由度超越了静态限制在淬火极限,并有可能描述的尺度依赖的现象,在自然界中看到的,当系统被充分激发时,新的强子产生。我指出,夸克的禁闭机制是相当不同的胶子和相应的一个嵌入在一个一致的框架,可以描述重要的定性性质的强相互作用物理,如手征对称性破缺,自发和异常质量产生和线性上升的重夸克势与几乎夸克质量独立的弦张力。

英文摘要:

Recently there has been progress in the understanding of the confinement mechanism in Landau gauge QCD. The emerging dynamical description in terms of the underlying gauge dependent degrees of freedom goes beyond the static confinement in the quenched limit and has the potential to describe the scale-dependent phenomenon seen in nature, where new hadrons are produced when the system is sufficiently excited. I point out that the confinement mechanism for quarks is rather different from the corresponding one for gluons and that both are embedded in a consistent framework that can describe important qualitative properties of strong interaction physics, like chiral symmetry breaking, spontaneous and anomalous mass generation and a linear rising heavy quark potential with an almost quark-mass independent string tension.
