论文摘要
随机拉普拉斯重物（LAPH）方法已被证明在耐药的计算中取得了成功。在这项工作中，考虑到魅力光谱，我们设置并优化了LAPH程序，将自己限制在两点中间相关函数的评估中。计算是在$ n_f = 2+1 $ 32^3 \ times64 $ lattice带有开放边界条件的CLS合奏上执行的。我们分析了液压参数与边界效应之间的相互作用，并实施了一个拟合程序以隔离从边界的激发。
The stochastic Laplacian Heaviside (LapH) method has proven to be successful in hadronic calculations. In this work, with charm-light spectroscopy in mind, we set up and optimise the LapH procedure limiting ourselves to the evaluation of two-point mesonic correlation functions. The calculations are performed on CLS ensembles with $N_f=2+1$ Wilson-Clover fermions on a $32^3\times64$ lattice with open boundary conditions. We analyse the interplay between the LapH parameters and the boundary effects, and implement a fitting procedure to isolate excitations coming from the border.
