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 cannot be obtained directly from the elastic scattering therefore, in this paper, we obtained the neutron structure function using the deep inelastic structure function of the proton and by applying the emc effect and the shadowing effect on the structure function of the deuteron. then, using the qcd theorem and re-analysis of the slac experiments e49, e61, e87, and e89 in deep inelastic electron-proton scattering at , we have extracted the up and down quark distribution functions, u_v (x),d_v (x), and also, using the appropriate model for the general parton distribution function, we plotted the dirac form factor the neutron. at the end, were compared the curves obtained in this work with the curves obtained in other models.
