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.journal article10.1103/physrevd.111.094512
