Nuclear Effect Parameter's Formula of the Nuclear Gluon Distribution Function

  • Based on the improved nuclear density model and the condition of the nuclear momentum conservation, we derived the formula of the nuclear effect parameter formula for the nuclear gluon distribution function, in which our established connection between the nuclear density and the mean binding energy in nucleus is used. By using the formula, we can well explain the experimental data of the J/ψ photoproduction in the l-A process.

Abstract: Based on the improved nuclear density model and the condition of the nuclear momentum conservation, we derived the formula of the nuclear effect parameter formula for the nuclear gluon distribution function, in which our established connection between the nuclear density and the mean binding energy in nucleus is used. By using the formula, we can well explain the experimental data of the J/ψ photoproduction in the l-A process.
