Query: Relativistic heavy ion collider as a photon factory: from GDR
  excitations to vector meson production   A variety of phenomena, which reveal itself in distant collisions of
ultrarelativistic nuclei is discussed. One or both nuclei may be disintegrated
in a single collision event by the long-range electromagnetic forces due to the
impact of the Lorentz-boosted Coulomb fields of collision partners.The process
is considered in the framework of the Weizs\"{a}cker-Williams method and
simulated by the RELDIS code, which takes into account all possible channels of
nuclear disintegration, including multiple neutron and proton emission and
meson production. Mutual electromagnetic dissociation of nuclei in peripheral
collisions can best be studied at RHIC and LHC. The contributions of
next-to-leading-order processes with multiple photon absorption of equivalent
photons by collision partners are considered in detail. As demonstrated, the
rates of the correlated forward-backward 2n and 3n emission are very sensitive
to the presence of double and triple excitations of Giant Resonances in
colliding nuclei. A practical application consists in the possibility of beam
luminosity monitoring in colliders via the registration of the correlated 1n
and 2n emission in mutual electromagnetic dissociation.
