Abstract
We compare the twist-2 and twist-4 parton distributions both in integrated and unintegrated parton distributions.We find that when x decreases the difference between the twist-2 and twist-4 parton distributions become obvious except for the valence quark distributions.We hope the future experiments may distinguish whether the twist-4 correction is needed or not and select a reasonable unintegrated parton distribution model.
