夸克-反夸克通量管和通量管复合的详细研究

Detailed study of quark-antiquark flux tubes and flux tube recombination

Marco Cardoso, Pedro Bicudo, Nuno Cardoso

摘要:

本文利用猝灭格点量子色动力学计算了静态夸克和静态反夸克之间的介体平面色场。特别地,我们看到夸克-反夸克距离对通量管的影响。为了获得这一结果,开发了改进的多击技术,并使用了扩展涂抹技术。然后,我们还讨论了两个夸克和两个反夸克组成的系统中的磁通管。研究了系统在不同配置下的基态和第一激发态场。

英文摘要:

In this work we compute the color fields in the mediator plane between a static quark and a static antiquark using quenched lattice QCD. In special, we see the effect of the quark-antiquark distance on the flux tube. To obtain this results an improved multihit technique is developed and an extend smearing technique is used. Then, we also discuss the flux-tubes in a system composed of two quarks and two antiquarks. The ground and first excited states fields are studied for different dispositions of the system.
