Abstract
We propose a modified definition for a quasiparton distribution function (QPDF) with an equal-time correlator in the large momentum limit, whose two pieces of spacelike Wilson links are oriented in orthogonal directions. It is explicitly shown at the one-loop level that the linear divergence in the original QPDF with dipolar Wilson links, which complicates its matching to the standard light-cone parton distribution function (LPDF), is removed. The LPDF can then be extracted reliably from Euclidean lattice data for the QPDF with the nondipolar Wilson links.
