The high flux of equivalent photons present in relativistic heavy ion collisions of two charges
Z 1 and Z 2 gives rise to the collision of two equivalent photons. The cross-sections for …

We study the γ− γ mechanism for relativistic heavy ions where the photon-photon interaction
occurs inside one of the nuclei. Strong absorption effects in overlapping collisions are also …

Effective γ− γ luminosities are calculated for various realistic hadron collider scenarios. The
main characteristics of photon-photon processes at relativistic heavy-ion colliders are …

The covariant and non-covariant Quantum Molecular Dynamics models are applied to
investigate possible relativistic effects in heavy ion collisions at SIS energies. These …

Direct photons have been proposed as a promising signature for the quark–gluon plasma
(QGP) formation in relativistic heavy-ion collisions. Recently WA98 presented the first data …

Using a covariant formalism we calculate to leading order the 2-photon contribution to lepton
pair production in coherent heavy ion collisions with-in the framework of EPA. The most …

The production of mesons in ultraperipheral collisions of relativistic heavy ions is reanalyzed
using a projection technique to calculate the amplitudes for the appropriate Feynman …

Electromagnetic effects in relativistic heavy ion collisions with impact parameter larger than
the sum of the nuclear radii are studied using the virtual photon method. With increasing …

Relativistic heavy ion beams are an intense source of (quasireal) photons with a spectrum
extending up to several hundred GeV, due to the high charge Z and the large energy of the …

Highly charged relativistic heavy ions have high cross sections for two-photon interactions.
The photon flux is high enough that two-photon interactions may be accompanied by …
