| Abstract: | The purpose of this paper is to calculate the longitudinal structure function of proton through the well-known equation F L =F 2?2xF 1. To determine this structure function, we need to identify parton distribution functions to find F 2. In this case, the valon model and DGLAP equations are utilized to obtain the parton distributions. Our calculations are carried out in two approximations LO and NLO. The results at the NLO approximation are in better agreement with the experimental data. |
