摘要:

本文介绍了格点量子色动力学中重子和介子激发态能谱计算的进展。研究了空间扩展强子算符的关联矩阵,证明了它们在激发态能量提取中的有效性。首先应用随机LapH方法,一种新的方法估计的低洼的影响夸克传播,提出。

英文摘要:

Progress in calculating the spectrum of excited baryons and mesons in lattice QCD is described. Correlation matrices of sets of spatially-extended hadron operators have been studied and their effectiveness in facilitating the extraction of excited-state energies is demonstrated. First applications of the stochastic LapH method, a new method of estimating the low-lying effects of quark propagation, are presented.
