Photon-Photon and Photon-Hadron Physics at Relativistic Heavy Ion Colliders
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. ...
متن کاملPhoton-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 کاملPhysics at High Energy Photon Photon Colliders
I review the physics prospects for high energy photon photon colliders, emphasizing results presented at the LBL Gamma Gamma Collider Workshop. Advantages and difficulties are reported for studies of QCD, the electroweak gauge sector, supersymmetry, and electroweak symmetry breaking. This work was supported by the Director, Office of Energy Research, Office of High Energy and Nuclear Physics, D...
متن کاملPhoton Production and Photon-Hadron Correlations in Relativistic Heavy Ion Collisions
We calculate the production of real photons in relativistic nuclear collisions at RHIC, consistently with the quenching of fast partons. We go beyond one-body observables, and evaluate photon-triggered fragmentation functions, in the kinematical window corresponding to that of experimental measurements.
متن کاملphoton-photon collisions via heavy ion beams at LHC
The cross sections for the production of hadrons in quasi real photonphoton collisions in heavy ion interactions are compared with the corresponding cross sections for central diffraction. The signatures, heavy ions with only slightly changed momenta together with two large rapidity gaps and a cluster of produced hadrons in the central region, are nearly identical in both processes. Therefore, ...
