Photon-Photon and Photon-Hadron Physics at Relativistic Heavy Ion Colliders
نویسنده
چکیده
The parton model is very useful to study scattering processes at very high energies. For example, nuclei consist of nucleons, which in turn consist of quarks and gluons, photons consist of lepton pairs, electrons of photons, etc.. Relativistic nuclei have photons as an important constituent at low enough virtuality Q = −q of the photon, due to the coherent action of all charges in the nucleus. The coherence condition limits the virtuality of the photons to

Photon-Photon and Photon-Hadron Interactions at Relativistic Heavy Ion Colliders
In central collisions at relativistic heavy ion colliders like the Relativistic Heavy Ion Collider RHIC/Brookhaven and the Large Hadron Collider LHC (in its heavy ion mode) at CERN/Geneva, one aims at detecting a new form of hadronic matter — the Quark Gluon Plasma. We discuss here a complementary aspect of these collisions, the very peripheral ones. Due to coherence, there are strong electroma...
متن کاملPhoton-Photon luminosities in relativistic heavy ion collisions at LHC energies
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 established and compared to the corresponding γ-γluminosities at e+-e−and future Photon Linear Colliders (PLC). Higher order corrections as well as inelastic processes are discussed. It is concluded that feasible h...

متن کاملCoherent photon-photon interactions in very peripheral relativistic heavy ion collisions
Heavy ions at high velocities provide very strong electromagnetic fields for a very short time. The main characteristics of ultraperipheral relativistic heavy ion collisions are reviewed, characteristic parameters are identified. The main interest in ultraperipheral heavy ion collisions at relativistic ion colliders like the LHC is the interactions of very high energy (equivalent) photons with ...
