Title: STATISTICAL MODEL OF PARTONS IN NUCLEON, EMC EFFECT AND GLUE DISTRIBUTION FUNCTIONS OF NUCLEON
Abstract: Assuming a nucleon as a thermodynamical system composed of partons (quarks and glue), we have disoussed its temperation T and chemical potential μ and nave derived relations between the x distribution functions of partons in the nucleon and its correspond statistical distribution functions. Through comparing glue of the nucleon with photons of the black-body, we have got effective temperature of the nucleon. By assuming μ of u. d quark to be the same and choosing their reasonable values, and after using the rescaling scheme to determine T of the mucleon, the statistical model could explain the EMC effect very well. If the gluon's chemical potential has a small and negative quantity, the statistical model could also fit the ratio R_g in μ+N→J/ψ+X process quite well and could explain why it seems too large in the small x region.
