Abstract
We investigate the valence quark distribution function of the pion in the framework of the chiral constituent quark model and evaluate the meson cloud effects on . We explicitly demonstrate how the meson cloud effects affect in detail. We find that the meson cloud correction causes an overall 32% reduction of the valence quark distribution and an enhancement at the small Bjorken regime. Besides, we also find that the dressing effect of the meson cloud will make the valence quark distribution to be softer in the large region.
