论文摘要
我们提供了SU（3）来自具有不同小晶格间距的五个合奏的混合静态电势的晶格Yang-mills数据，以及Quark-Antiquark分离的相应参数化$ 0.08 \，\ \ \ text {fm} {fm} \ le r \ le r \ le r \ le r \ le 1.12 \，\ fext {fm {fm} $。我们在扰动理论的树级别上删除了晶格离散错误，部分是在$ a^2 $的顺序上以及$ a $ a的依赖性自我。特别是详细讨论了静态电势的树级改进，并比较了两种方法。预期所得的参数化代表统计误差内混合静态电位的连续限制结果。
We present SU(3) lattice Yang-Mills data for hybrid static potentials from five ensembles with different small lattice spacings and the corresponding parametrizations for quark-antiquark separations $0.08\,\text{fm} \le r \le 1.12\,\text{fm}$. We remove lattice discretization errors at tree level of perturbation theory and partly at order $a^2$ as well as the $a$-dependent self energy. In particular the tree-level improvement of static potentials is discussed in detail and two methods are compared. The resulting parametrizations are expected to represent continuum limit results for hybrid static potentials within statistical errors.
