SU（3）规范不变的格点量子色动力学对通量管聚变、对偶胶子质量和对偶金兹伯格-朗道参数下对偶超导体图象的探索
SU(3) gauge invariant lattice QCD exploration of the dual superconductor picture in flux tube fusion, in the dual gluon mass, and in the dual Ginzburg-Landau parameters
摘要：
本文在猝灭SU（3）格点量子色动力学、$24^3\times 48$格点的$β=6.2$和$a=0.07261(85)\,fm$上计算了静态胶子-夸克-反夸克系统的色场。我们计算了混合威尔逊圈，包括胶子和反夸克叠加的情况，即。例如，夸克-反夸克情形以及夸克和反夸克叠加时，即.例如，胶子-胶子的例子研究了Casimir标度，在双胶子胶球情形下，Casimir标度与伴随弦的形成是一致的。通过测量双胶子胶球和夸克-反夸克介子在流管中段的尾衰变，确定了穿透长度，并给出了规范不变的有效对偶胶子质量$0.905\pm0.163\,\text{GeV}$ .我们还试图确定的相干长度比较我们的结果与双金兹伯格-朗道的方法。与穿透长度和可能的相干长度，我们确定了一个假定的金兹伯格-朗道无量纲参数，这可能是符合第二类超导图片。这些结果是在固定的夸克-反夸克距离为0.58 fm时得到的。
英文摘要：
The colour fields, created by a static gluon-quark-antiquark system, are computed in quenched SU(3) lattice QCD, in a $24^3\times 48$ lattice at $β=6.2$ and $a=0.07261(85)\,fm$. We compute the hybrid Wilson Loop including the cases when the gluon and the antiquark are superposed, i. e., the quark-antiquark case and when the quark and antiquark are superposed, i. e., the gluon-gluon case. The Casimir scaling is investigated, in the two gluon glueball case the Casimir scaling is consistent with the formation of an adjoint string. Measuring the decay of the tail in the mid section of the flux tube for the two gluon glueball and for the quark-antiquark meson, we determine the penetration length and present a gauge invariant effective dual gluon mass of $0.905\pm0.163\,\text{GeV}$. We also try to determine the coherence length comparing our results with the dual Ginzburg-Landau approach. With the penetration length and the possible coherence length we determine a putative Ginzburg-Landau dimensionless parameter, which is possibly consistent with a type II superconductor picture. These results are obtained at fixed quark-antiquark distance of 0.58 fm.
