The improved saturation model in nuclei

Abstract

We consider the nuclear shadowing in deep-inelastic scattering corresponding to kinematic regions accessible by future experiments at electron-ion colliders. The gluon distribution at small $x$ is obtained using an improved dipole model depended on the impact parameter for atomic nucleus and compared with nCETQ15 parametrization group. The nuclear shadowing at small $x$ is defined within the color dipole formalism with respect to the mass number $A$. Its behavior is predicted for light nuclei in a wide range of the impact parameter $b$ and the transverse dipole size $r$. The nuclear saturation at large-$r$ (small ${\mu }^2$) is observable. The behavior of the nuclear ratio ${\sigma }_{\mathrm{dip}}^A/{\sigma }_0$ is similar to the Golec-Biernat-W$\ddot{\mathrm{u}}$sthoff (GBW) model in a wide range of $r$ for light and heavy nuclei at small $x$.
