Meson cloud effects on the pion quark distribution function in the chiral constituent quark model

Akira Watanabe, Chung Wen Kao, Katsuhiko Suzuki

We investigate the valence quark distribution function of the pion $v^{\pi }(x,Q^2)$ in the framework of the chiral constituent quark model and evaluate the meson cloud effects on $v^π(…
