  The higher twist effects in deep inelastic scattering on the nuclear target
are studied using time ordered perturbation theory. We showed that the
collinear rescattering of the outgoing quark on the extra nucleons via the
contacting gluon-pair is dominant in nuclear size-dependent effects. The
Qiu-Vitev resummation is proved by using the geometric properties of the higher
twist amplitudes. The leading contributions of nuclear-enhanced effect to the
DGLAP evolution equation are resummed in the same framework.
