Interplay of Reggeon and photon in pA collisions

Abstract

We discuss the effects of the electromagnetic interaction in high-energy proton collisions with nuclei of large Z at strong coupling $\lambda =g^2{N}_c$. Using the holographic dual limit of large $N_c>\lambda \gg 1$, we describe the Reggeon exchange as a twisted surface and show that it gets essentially modified by the electromagnetic interaction.
