STATISTICAL MODEL OF PARTONS IN NUCLEON,EMC EFFECT AND GLUE DISTRIBUTION FUNCTIONS OF NUCLEON

  • 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 Rg in μ+N→J/ψ+X process quite well and could explain why it seems "too large" in the small x region.

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 Rg in μ+N→J/ψ+X process quite well and could explain why it seems "too large" in the small x region.
