论文摘要
我们在具有夸克内容$ \ bar {b} \ bar {b} ud $，$ \ bar {b} \ bar {b} us $和$ \ bar {b bar {b bar {b bar {c} ud $使用lattice qcd。我们在几个量规链路上进行计算，并使用$ n_f = 2+1 $域壁式费米子的风味，并考虑局部和非本地插值器的基础。除了从相关矩阵中提取能谱外，我们还进行了吕舍尔分析，以推断我们的结果到无限的体积。
We search for possibly existent bound states in the heavy-light tetraquark channels with quark content $ \bar{b}\bar{b}ud $, $ \bar{b}\bar{b}us $ and $ \bar{b}\bar{c}ud $ using lattice QCD. We carry out calculations on several gauge link ensembles with $ N_f=2+1 $ flavours of domain-wall fermions and consider a basis of local and non-local interpolators. Besides extracting the energy spectrum from the correlation matrices, we also perform a Lüscher analysis to extrapolate our results to infinite volume.
