I consider particle production in high-energy pA collisions. In addition to the coherent interactions with the nuclear color field, I take into account coherent interactions with the nuclear electromagnetic Coulomb field. Employing the dipole model, I sum up the leading multiple color and electromagnetic interactions and derive inclusive cross sections for photon and dilepton production. I found that the Coulomb corrections are up to 10% at √ s = 200 GeV per nucleon.
