摘要

Peripheral collisions of relativistic heavy ions uniquely probe many aspects of QED. Examples include e~+ e~- pair production and nuclear excitation in strong fields. After discussing these reactions, I will draw parallels between γ → e~+e~- and γ → qq and consider partly hadronic reactions. The scattered qq pairs are a prolific source of vector mesons, which demonstrate many quantum effects. The two ions are a two-source interferometer, demonstrating interference between meson waves. Multiple vector meson production will demonstrate superradiance, a first step toward a vector meson laser. Finally, I will discuss the experimental program planned at the RHIC and LHC heavy ion colliders.
