Abstract
The one loop matching kernels between parton distribution functions (PDFs) for parton i=u, d, s, g and their corresponding quasi-PDFs are computed at one loop in the hybrid-ratio scheme. We found that, in addition to the conservation of the quasiquark number for each flavor, the second moment x ĩ=x i of quasi-PDF of parton i (denoted as ĩ) and PDF of parton i is the same in our approach. This is demonstrated numerically using the CTEQ14 global analysis as input.
