Photoproduction reactions occur when the electromagnetic field of a relativistic heavy ion
interacts with another heavy ion. The STAR Collaboration presents a measurement of ρ 0 …

Direct real photons are arguably the most versatile tools to study relativistic heavy ion
collisions. They are produced, by various mechanisms, during the entire space-time history …

We present results about photon-production in relativistic heavy-ion collisions. The main
novelty of our study is the calculation of the contribution of the early-stage photons to the …

We study mutual dissociation of heavy nuclei in peripheral collisions at ultrarelativistic
energies. Earlier this process was proposed for beam luminosity monitoring via …

This work studies the production of direct photons in relativistic nuclear collisions, along with
the production of hadrons. Radiation from the very first instants to the final moments of the …

The cross sections for the production of hadrons in quasi-real photon-photon collisions in
proton-proton and heavy ion interactions are compared with the corresponding cross …

We study the transverse momentum distribution of vector mesons produced in
ultraperipheral relativistic heavy ion collisions (UPCs). In UPCs there is no strong interaction …

Two-photon correlations are discussed within the formalism of Hanbury-Brown and Twiss
interferometry and Bose-Einstein correlations. The technique is presented as a universal …

The probabilities of electron-positron pair creation with K-shell capture, of ionization, and of
excitation are nonperturbatively calculated with a finite-difference method. Calculations for a …

Light nuclei can be produced in the central reaction zone via coalescence in relativistic
heavy-ion collisions. Experiment 864 at BNL has measured the production of ten light nuclei …
