摘要:

动力学组态上的强子谱面临着处理单粒子态和多强子态混合的困难(对于大空间体积和轻动力学夸克质量)。可以想象的是,显式的多强子插值算子将是必要的,以获得足够好的重叠到多个强子状态,以提取低位激发谱。我们在这里探讨的可行性,使用四个噪音稀释的全对全夸克传播子在淬火,各向异性晶格上的显式双强子算子的建设。我们的长期目标是使用这些运营商的大型各向异性,动力学配置的强子光谱。

英文摘要:

Hadron spectroscopy on dynamical configurations are faced with the difficulties of dealing with the mixing of single particle states and multi-hadron states (for large spatial volumes and light dynamical quarks masses). It is conceivable that explicit multi-hadron interpolating operators will be necessary for obtaining sufficiently good overlap onto multi-hadron states in order to extract the low-lying excitation spectrum. We explore here the feasibility of using four noise diluted all-to-all quark propagators in the construction of explicit two-hadron operators on quenched, anisotropic lattices. Our longer term goal is to use these operators on large anisotropic, dynamical configurations for hadron spectroscopy.
