Measurement of Mutual Coulomb Dissociation in 130 GeV/A Au+Au collisions at RHIC
We report on the first measurement of Mutual Coulomb Dissociation in Heavy Ion Collisions. We employ forward calorimeters to measure neutron multiplicity at Beam rapidity in peripheral collisions. The measured cross section for simultaneous electromagnetic breakup of Au nuclei at 130 GeV/A is 3.6 barns in good agreement with calculations.

Photon-photon and photon-hadron physics at relativistic heavy ion colliders
Due to the coherence, there are strong electromagnetic fields of short duration in peripheral relativistic heavy ion collisions.
They give rise to photon-photon and photon-nucleus collisions with a high flux of quasireal photons. We discuss photon-photon luminosities that can be reached at the LHC as well as photonuclear processes. Electron-positron pairs are produced copiously in these collisions; they are a possible background process and an important source for beam loss.
