强耦合极限下QCD的重子袋模拟

Baryon bag simulation of QCD in the strong coupling limit

Oliver Orasch, Shailesh Chandrasekharan, Christof Gattringer, Pascal Törek

摘要:

我们探讨了用重子袋模拟强耦合QCD的可能性。在这种形式中,已知的单体、二聚体和重子环的表示被重组,使得重子贡献被收集在称为重子袋的时空域中。在袋中,三个夸克作为一个重子相干地传播,重子由自由费米子描述,而晶格的其余部分仅充满相互作用的介子项,即,夸克和双夸克单体和二聚体。我们直接在重子袋语言中使用新开发的蠕虫更新进行模拟,并在两个维度上显示第一个结果。

英文摘要:

We explore the possibility of a simulation of strong coupling QCD in terms of so-called baryon bags. In this form the known representation in terms of monomers, dimers and baryon loops is reorganized such that the baryon contributions are collected in space time domains referred to as baryon bags. Within the bags three quarks propagate coherently as a baryon that is described by a free fermion, whereas the rest of the lattice is solely filled with interacting meson terms, i.e., quark and diquark monomers and dimers. We perform a simulation directly in the baryon bag language using a newly developed worm update and show first results in two dimensions.
