我表明，与夸克和胶子在光锥上的关联相关的部分子物理可以通过在大动量极限下的帧相关的等时算符的矩阵元来研究。这一观测结果允许在欧几里得晶格上对部分子性质进行实际计算。作为一个例子，我演示了如何恢复领先的扭曲夸克分布，通过提高一个大的动量的等时相关。
I show that the parton physics related to correlations of quarks and gluons on the light cone can be studied through the matrix elements of frame-dependent, equal-time correlators in the large momentum limit. This observation allows practical calculations of parton properties on a Euclidean lattice. As an example, I demonstrate how to recover the leading-twist quark distribution by boosting an equal-time correlator to a large momentum.
