Interplay of Reggeon and photon in pA collisions
arXiv:1703.06078 · doi:10.1103/PhysRevD.95.126005
Abstract
We discuss the effects of the electromagnetic interaction in high-energy proton collisions with nuclei of large Z at strong coupling $λ=g^2N_c$. Using the holographic dual limit of large $N_c>λ\gg 1$, we describe the Reggeon exchange as a twisted surface and show that it gets essentially modified by the electromagnetic interaction.
