The Parton Distribution Functions and Calculation of Dirac Neutron Form Factor Considering the EMC and Shadowing Effects

Due to the absence of the free neutron target, the form factors or the structure function of the neutron directly cannot be obtained from the elastic scattering data. Therefore, in this paper, we obtained the neutron structure function using the deep inelastic structure function of the proton and by applying the EMC and the shadowing effects on the structure function of the deuteron. Then, using the quantum chromo dynamics theorem and re-analysis of data from the SLAC experiments E49, E61, E87, and E89 in electron–proton deep inelastic scattering at Q 2 = 1–20 GeV 2 , we have extracted the up and down quark distribution functions, ( x ), ( x ), and also, using an appropriate model for the general parton distribution function, we have plotted the Dirac form factor of the neutron. At the end, the curves obtained in this work were compared with the curves obtained in other models.
