Lasse Mueller, Owe Philipsen, Christian Reisinger, Marc Wagner

摘要:

本文计算了SU(2)和SU(3)格点规范理论中混合静电势的色电和色磁通量密度。除了普通的静电势与量子数$Λ_η^ε= Σ_g^+$,我们提出了7个混合静电势对应的$Λ_η^{(ε)} = Σ_u^+, Σ_g^-, Σ_u^-, Π_g, Π_u, Δ_g, Δ_u$,其中5个的通量密度的数值结果进行了研究,在这项工作中的第一次。我们观察到的混合静电势通量管,这是显着不同的,从普通的静电势。它们让人想起振动的弦,在通量密度中有局部峰值,可以解释为价胶子。

英文摘要:

We compute chromoelectric and chromomagnetic flux densities for hybrid static potentials in SU(2) and SU(3) lattice gauge theory. In addition to the ordinary static potential with quantum numbers $Λ_η^ε= Σ_g^+$, we present numerical results for seven hybrid static potentials corresponding to $Λ_η^{(ε)} = Σ_u^+, Σ_g^-, Σ_u^-, Π_g, Π_u, Δ_g, Δ_u$, where the flux densities of five of them are studied for the first time in this work. We observe hybrid static potential flux tubes, which are significantly different from that of the ordinary static potential. They are reminiscent of vibrating strings, with localized peaks in the flux densities that can be interpreted as valence gluons.
