标题： The excited hadron spectrum in lattice QCD using a new method of estimating quark propagation

摘要： 晶格QCD中确定激发态重子和介子谱的进展被描述。 已经研究了大量精心设计的强子算符，并展示了它们在提取激发态能量方面的有效性。 提出了一种随机估算夸克传播低能效应的新方法，这将允许可靠地确定单强子和多强子算符的时间相关性。 显示英文摘要

摘要： Progress in determining the spectrum of excited baryons and mesons in lattice QCD is described. Large sets of carefully-designed hadron operators have been studied and their effectiveness in facilitating the extraction of excited-state energies is demonstrated. A new method of stochastically estimating the low-lying effects of quark propagation is proposed which will allow reliable determinations of temporal correlations of single-hadron and multi-hadron operators.
