$N_f=2$ Clover-Wilson晶格中的低自旋和高自旋介子

Low and high spin mesons from $N_f=2$ Clover-Wilson lattices

Tommy Burch, Christian Hagen, Martin Hetzenegger, Andreas Schäfer

摘要:

本文给出了CP-PACS协作组提供的$N_f=2$三叶草-威尔逊组态激发介子谱的结果。在我们的研究中,我们研究了低自旋和高自旋介子。对于自旋为0和自旋为1的介子,我们对激发态特别感兴趣。为了访问这些状态,我们从不同的空间拖尾的夸克源构建几个不同的插值器,并计算一个矩阵的插值器。对于这个矩阵,我们然后解决一个广义特征值问题。对于自旋2和自旋3,我们只提取最低的躺态。

英文摘要:

We present results for excited meson spectra from $N_f=2$ clover-Wilson configurations provided by the CP-PACS Collaboration. In our study we investigate both low and high spin mesons. For spin-0 and spin-1 mesons, we are especially interested in the excited states. To access these states we construct several different interpolators from quark sources of different spatial smearings and calculate a matrix of correlators. For this matrix we then solve a generalized eigenvalue problem. For spin-2 and spin-3, we extract only the lowest lying states.
