摘要:
We use the refined hot spot model to study the valence quark shape of the proton with the deeply virtual Compton scattering at high energies in the framework of Color Glass Condensate. To investigate the individual valence quark shape, a novel treatment of the valence quark width is employed. We calculate the cross-sections for the coherent and incoherent deeply virtual Compton scattering, for the first time, by using different widths ($\mathrm{B_u}$ and $\mathrm{B_d}$) for the profile density distributions of the up and down quarks instead of using the same width as in the literature. We find...
