Abstract: The statistical model is applied to study the parton distribution function of the K and
the π mesons. By using the parameterized form for the parton distribution function of the meson
obtained from the statistical model and combining the meson induced Drell-Yan data,the u quark
distribution function of the K meson is extracted, the values of the parameters are
determined. The extraction shows that the statistical approach can describe the ratio of the
K-nucleon Drell-Yan and π-nucleon fairly well. It is also found that the chemical potential of
the u quark with positive helicity inside the K meson is larger than that inside the π meson.
Key words: parton distribution function, statistical model, chemical potential
