We perform a perturbative QCD analysis of the nucleon’s Pauli form factor [Formula presented] in the asymptotically large [Formula presented] limit. We find that the leading contribution to [Formula presented] has a [Formula presented] power behavior, consistent with the well-known result in the literature. Its coefficient depends on the leading- and subleading-twist light-cone wave functions of the nucleon, the latter describing the quarks with one unit of orbital angular momentum. We also derive at the logarithmic accuracy the asymptotic scaling [Formula presented] which describes recent Jefferson Lab data well.
