标题： In-medium heavy quarkonium from lattice NRQCD

摘要： 我们呈现了对重夸克胶子束缚态介质中谱性质多年研究的最终结果。 在这项工作中，我们将HotQCD合作组提供的高统计量$N_f=2+1$族与有效理论NRQCD和改进的贝叶斯谱重构方法相结合。 我们以高精度验证了介质中夸克胶子态相对于其真空结合能的分层修改，并提供了更新的熔化温度值。 特别是，我们能够理解不同贝叶斯方法之间的先前分歧是由于系统不确定性的低估所致。 主要定量结果是对介质中夸克胶子基态质量位移的稳健确定，我们发现这些位移为负，与强耦合pNRQCD势计算中观察到的行为一致。 显示英文摘要

摘要： We present the final results from a multi-year study of the in-medium spectral properties of heavy quarkonium bound states on the lattice. In this work we combine high statistics $N_f=2+1$ ensembles from the HotQCD collaboration with the effective theory NRQCD and improved Bayesian spectral reconstruction methods. We corroborate with high precision the hierarchical in-medium modification of quarkonium states with respect to their vacuum binding energy and provide updated values on melting temperatures. In particular we are able to understand previous disagreements between different Bayesian methods as resulting from underestimated systematic uncertainties. The main quantitative result is a robust determination of the in-medium mass shifts of quarkonium ground states, which we find are negative, consistent with the behavior observed in strongly coupled pNRQCD potential based computations.
