论文摘要
我们计算静态夸克古夸克对之间形成的通量管的光谱,并使用pure $ su(3)$ sugue lattice qcd in $ 3+1 $。为了实现这一目标,我们使用了大量适当的操作员,各向异性t t改进了动作,涂抹技术并解决了广义特征值问题。此外,我们将结果与Nambu-Goto弦模型进行了比较,以评估可能是新现象的信号的紧张局势。
We compute the spectra of flux tubes formed between a static quark antiquark pair up to a significant number of excitations and for eight symmetries of the flux tubes, up to $Δ_u$, using pure $SU(3)$ gauge lattice QCD in $3+1$ dimensions. To accomplish this goal, we use a large set of appropriate operators, an anisotropic tadpole improved action, smearing techniques, and solve a generalized eigenvalue problem. Moreover, we compare our results with the Nambu-Goto string model to evaluate possible tensions which could be a signal for novel phenomena.
