论文摘要
我们报告了基于有限体积光谱法的核子核子散射的持续分析。使用$m_π= m_k \ $ m_k \ \ 420 $ MEV在su（3） - 对称点上使用八个晶格集合的蒸馏方法进行计算，涵盖了一系列的晶格间距和量，并以前用于研究$ h $ dibaryon。我们获得了$ s $，$ p $，$ d $和$ f $ waves的非零信号，以及spin-1 $ s $和$ d $ waves之间的混合。对于$ s $波浪，晶格伪像很重要，并且倾向于加强巴里昂 - 巴里昂的相互作用。在Deuteron和Dineutron $ s $ Waves中，我们找到了虚拟界面状态。
We report an ongoing analysis of nucleon-nucleon scattering based on finite-volume spectroscopy. The calculation is performed using the distillation method on eight lattice ensembles at the SU(3)-symmetric point with $m_π=m_K\approx 420$ MeV generated by CLS, covering a range of lattice spacings and volumes and previously used to study the $H$ dibaryon. We obtain nonzero signals for $S$, $P$, $D$, and $F$ waves as well as the mixing between spin-1 $S$ and $D$ waves. For $S$ waves, lattice artifacts are significant and tend to strengthen baryon-baryon interactions. In the deuteron and dineutron $S$ waves, we find virtual bound states.
