基于动量守恒和阿贝尔-希格斯（AH）模型，研究了静态夸克和反夸克系统中通量管周围的应力张量分布。我们首先研究了动量守恒对应力张量分布的约束，并表明边界的影响在描述SU(3) Yang-Mills理论中的通量管结构方面起着至关重要的作用，该理论最近在晶格上进行了测量[R]。Yanagihara， T. ititani， M. Kitazawa， M. Asakawa和T. Hatsuda，物理学家。列托人。[j].生物工程学报，2016,31(5)。然后，我们研究了在AH模型中有边界和无边界的磁涡旋周围的应力张量和能量密度的分布，并将它们与SU(3)基于对偶超导体图的Yang-Mills理论中的分布进行了比较。通过与晶格结果的应力张量的比较表明，AH模型排除了较宽的参数范围。
We study the stress-tensor distribution around the flux tube in static-quark and anti-quark systems based on the momentum conservation and the Abelian–Higgs (AH) model. We first investigate constraints on the stress-tensor distribution from the momentum conservation and show that the effect of boundaries plays a crucial role in describing the structure of the flux tube in SU(3) Yang–Mills theory, which has recently been measured on the lattice [R. Yanagihara, T. Iritani, M. Kitazawa, M. Asakawa, and T. Hatsuda, Phys. Lett. B789, 210 (2019)]. We then study the distributions of the stress tensor and energy density around the magnetic vortex with and without boundaries in the AH model, and compare them with the distributions in SU(3) Yang–Mills theory based on the dual superconductor picture. It is shown that a wide parameter range of the AH model is excluded by a comparison with the lattice results in terms of the stress tensor.
