QCD Analysis for Nuclear Parton Distributions in the Next to Leading Order

Abstract

A QCD analysis of the nuclear parton distributions and structure functions in the NLO is performed by using the world data. By having bounded parton distributions for a nuclear with atomic number A, we can obtain the nuclear structure function in x space. Our results for nuclear structure function ratio $F_2^A/F_2^D$ for some different values of A, are in good agreement with the experimental data. We compare our results for LO and NLO approximation.
