Description
After an introduction of the concept of Saturation occurring in nuclear physic, we develop the Color Glass Condensate formalism through a specific event of proton-nuclei collisions, the photon-Jet production. In the present work we consider the first correction to the nuclei's size, the Next-to-Eikonal (NEik) approximation. The differential cross section of the process is found to be factorised for particles produced back-to-back. In accordance with previous results found at NCBJ, the small x value probing the gluon distribution is fixed by subeikonal effects together with the back-to-back expansion.
