摘要

利用晶格微扰理论研究了连续体与晶格间拟部分子分布函数的匹配问题,特别是威尔森型费米子。对空间方向上具有直Wilson线的非局部夸克双线性算子进行了匹配。我们还研究了基于格上对称参数的非局部算子在重整化中的混合算子和可能的O(a)算子。

Perturbative matching of continuum and lattice quasi-distributions
Matching of the quasi parton distribution functions between continuum and lattice is addressed using lattice perturbation theory specifically with Wilson-type fermions. The matching is done for nonlocal quark bilinear operators with a straight Wilson line in a spatial direction. We also investigate operator mixing in the renormalization and possible O(a) operators for the nonlocal operators based on a symmetry argument on lattice.
