Parton distribution functions of ground state mesons composed of $c$ or $b$ quarks

Qian Wu, Zhu-Fang Cui, Jorge Segovia

The valence quark parton distribution functions (PDFs) of all ground state heavy mesons that composed of $b$ or $c$ quarks, are discussed; namely, the pseudoscalar ${\eta }_c(1S)$, $η_b(…
