Photoproduction of and in pp and Collisions
Spencer Klein, Joakim Nystrand
Exclusive vector meson photoproduction, and occurs with significant rates at hadron colliders. The reaction can be used to study the gluon distribu…
Electrodynamics at the Highest Energies
Spencer R. Klein
At very high energies, the bremsstrahlung and pair production cross sections exhibit complex behavior due to the material in which the interactions occur. The cross sections in den…
Nonlinear QED Effects in Heavy Ion Collisions
Spencer R. Klein
Peripheral collisions of relativistic heavy ions uniquely probe many aspects of QED. Examples include pair production and nuclear excitation in strong fields. After discus…
Two-Photon Physics in Nucleus-Nucleus Collisions at RHIC
Joakim Nystrand, Spencer Klein, the STAR Collaboration
Ultra-relativistic heavy-ions carry strong electromagnetic and nuclear fields. Interactions between these fields in peripheral nucleus-nucleus collisions can probe many interesting…
The LPM Effect: Comparing SLAC E-146 Data with Experiment
Spencer R. Klein
The suppression of photon bremsstrahlung due to a variety of in-medium effects is discussed. Different electrodynamic suppression effects are discussed, and compared with the relat…
The Gold Flashlight: Coherent Photons (and Pomerons) at RHIC
Spencer Klein, Evan Scannapieco
The Relativistic Heavy Ion Collider (RHIC) will be the first heavy ion accelerator energetic enough to produce hadronic final states via coherent \gamgam, \gampom, and \pompom inte…
