我们提出一种新方案，通过研究不同维克收缩的图形，可以用以分辨强子的内部结构信息。我们对ρ介子中ππ到ππ的两类维克收缩图进行计算，可以清楚看到当四条夸克线都是从soure到sink的情况下，并不会出现ρ介子的能级贡献，这表明ρ中的两夸克成分是主要的。
Understanding the partonic structure of hadrons from first principles is a major goal of lattice QCD. In this talk, I will review recent progress by the Lattice Parton Collaboration using large-momentum effective theory (LaMET). I will first discuss lattice determinations of longitudinal parton structure, including parton distribution functions and light-cone distribution amplitudes of mesons...
We present a lattice QCD study of the $K^*(892)$ resonance using
eight $N_f=2+1$ Wilson-Clover ensembles with three lattice spacings
and six pion masses ranging from 135 to 320 MeV. For each ensemble,
a large number of finite volume energy levels in the $P$-wave $K\pi$
channel are determined. The energy dependence of the scattering
phase shift is then obtained from L\"uscher’s...
