论文摘要
蒸馏框架中优化的梅森运算符用于研究两个合奏中的炭谱,其中两个重型动态夸克在物理魅力夸克质量一半,但晶格间距不同。证明最佳介子蒸馏曲线的使用可显着增加与基态的重叠,以及对激发状态的赠款访问,包括多个量子数字,包括混合状态,几乎没有额外的成本。这些相同的操作员也用于计算介子 - 胶合球混合。
Optimized meson operators in the distillation framework are used to study the charmonium spectrum in two ensembles with two heavy dynamical quarks at half the physical charm quark mass but different lattice spacings. The use of optimal meson distillation profiles is shown to increase the overlap with the ground state significantly, as well as grant access to excited states, for multiple quantum numbers including hybrid states with very little additional cost. These same operators are also employed for the calculation of meson-glueball mixing.
