论文摘要
从晶状体QCD（LQCD）中提取有限摩托马州的Hadronic可观测值受到所有此类LQCD计算的众所周知的信号到噪声问题的约束。传统的Quark涂抹算法是通常使用的工具，可以提高操作员Momenta很小的HADRONIC $ N $点功能的统计质量。 Bali等人的动量涂抹算法。扩展了可干净访问的动量范围，并促进了无数新颖的晶格计算。然而，在蒸馏框架内，动量涂抹并未明确证明。在这项工作中，我们通过探索对蒸馏框架的一些修改来扩展势头的想法。加上增强的时间切片采样和扩展的操作员群，我们发现可以可靠地提取地面核能能量，以$ \ left | \ weft | \ vec {p} \ right | \ right | \ lyseSim3 \ listsim3 \ text {gev} $和矩阵元素以及具有大型动量依赖性的依赖性。
Extraction of hadronic observables at finite-momenta from Lattice QCD (LQCD) is constrained by the well-known signal-to-noise problems afflicting all such LQCD calculations. Traditional quark smearing algorithms are commonly used tools to improve the statistical quality of hadronic $n$-point functions, provided operator momenta are small. The momentum smearing algorithm of Bali et al. extends the range of momenta that are cleanly accessible, and has facilitated countless novel lattice calculations. Momentum smearing has, however, not been explicitly demonstrated within the framework of distillation. In this work we extend the momentum-smearing idea, by exploring a few modifications to the distillation framework. Together with enhanced time slice sampling and expanded operator bases engendered by distillation, we find ground-state nucleon energies can be extracted reliably for $\left|\vec{p}\right|\lesssim3\text{ GeV}$ and matrix elements featuring a large momentum dependence can be resolved.
