论文摘要
根据Ji〜 \ cite {PhysRevlett.110.262002}的开创性建议，对欧几里得晶格上量子Chromo Dynamics（QCD）的数值模拟提供了有关Hadrons结构的新的，有价值的信息。在这次演讲中，我们简要回顾了重建Parton密度的晶格方法，突出了晶格可观察物与Parton密度之间的联系，重点是理论问题。由于Parton分布是通过解决逆问题从晶格数据中提取的，因此我们讨论了一些影响这些决定的困难以及如何在贝叶斯框架中配制它们的困难。
Following a ground-breaking proposal by Ji~\cite{PhysRevLett.110.262002}, numerical simulations of Quantum Chromo Dynamics (QCD) on a Euclidean lattice have provided new, valuable information on the structure of hadrons. In this talk, we briefly review the lattice approach to the reconstruction of parton densities, highlighting the connection between lattice observables and parton densities, with a focus on theoretical issues. Since parton distributions are extracted from lattice data by solving an inverse problem, we discuss some of the difficulties that affect these determinations and how they can be formulated in a Bayesian framework.
