Approximation method for the nuclear structure functions at small x

Abstract

We have demonstrated that the relationship between the deep inelastic scattering structure functions remains stable for a nuclear target with mass number A at \(x{\le }10^{-3}\). Numerical results have been provided for the specific nuclei \(^{12}\)C and \(^{208}\)Pb using the nuclear PDF parametrisations incorporated in the HIJING2.0 model. These findings are within the electron–ion collider kinematic acceptance for heavy ion running. The ratio \(R^{A}_{F_{L}}\) is determined as the ratio \(R^{A}_{F_{2}}\) based on the HIJING2.0 model.
