摘要
我们提出了一个用O(a)改进的威尔逊费米子在$n_f=2$ QCD中两个静态夸克之间的势的初步计算。我们探讨了不同的涂抹选择(HYP, HYP2和APE)及其对计算静态电位信噪比的影响。这是一项更大的努力的一部分，首先是精确计算QCD弦断裂参数，并随后将其用于基于Born-Oppenheimer近似(Bicudo et al. 2020 \cite{Bicudo:2019ymo})的最新方法，以研究夸克粒子共振和束缚态。
We present a preliminary computation of potentials between two static quarks in $n_f=2$ QCD with O(a) improved Wilson fermions. We explore different smearing choices (HYP, HYP2 and APE) and their effect on the signal to noise ratio in the computed static potentials. This is a part of a larger effort concerning, at first, a precise computation of the QCD string breaking parameters and their subsequent utilization for the recent approach based on Born-Oppenheimer approximation (Bicudo et al. 2020 \cite{Bicudo:2019ymo}) to study quarkonium resonances and bound states.
