标题： Decoding Two-Particle States in QCD with Spatial Wavefunctions

摘要： 一种系统的方法来构建与QCD两粒子态强耦合的优化插值算符被开发出来，这是通过结合介子间的空间波函数实现的。 为了在格点QCD中高效地实现这些算符，提出了一种利用噪声向量的新夸克平滑技术。 应用于$\Omega_{ccc}\Omega_{ccc}$系统，优化的算符在阈值$2m_{\Omega_{ccc}} \simeq 9700$ MeV附近分辨出仅相隔$\sim 5$MeV的不同本征态。 这种卓越的分辨能力为QCD中广泛范围的强子系统的研究所提供了新的可能性。 显示英文摘要

摘要： A systematic way to constructing optimized interpolating operators strongly coupled to QCD two-particle states is developed, which is achieved by incorporating inter-hadron spatial wavefunctions. To efficiently implement these operators in lattice QCD, a novel quark smearing technique utilizing noise vectors is proposed. Applied to the $\Omega_{ccc}\Omega_{ccc}$ system, the optimized operators resolve distinct eigenstates separated by only $\sim 5$ MeV near the threshold $2m_{\Omega_{ccc}} \simeq 9700$ MeV. This exceptional resolving power opens new possibilities for studies of a wide range of hadronic systems in QCD.
