Exclusive vector meson production reactions such as Au+ Au→ Au+ Au+ V, where V= ρ, ω,
φ, or J/ψ, can proceed through photon-Pomeron and photon-meson interactions. Photons …

Relativistic heavy ions are copious sources of virtual photons. The large photon flux gives
rise to a substantial photonuclear interaction probability at impact parameters where no …

Vector mesons are produced copiously in peripheral relativistic heavy-ion collisions. Virtual
photons from one ion can fluctuate into quark-antiquark pairs and scatter from the second …

We make predictions for the cross sections of coherent photoproduction of ρ, ϕ, J/ψ, ψ (2 S),
and Υ (1 S) mesons in Pb-Pb ultraperipheral collisions (UPCs) at s NN= 5.02 TeV in the …

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 …

We discuss the photoproduction of Υ and J/ψ at high energy p¯ p, pp, and heavy ion
colliders. We predict large rates in p¯ p interactions at the Fermilab Tevatron and in pp and …

Direct photons have been proposed as a promising signature for the quark–gluon plasma
(QGP) formation in relativistic heavy-ion collisions. Recently WA98 presented the first data …

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 …

Significant excesses of J/ψ yield at very low transverse momentum (p T< 0.3 GeV/c) were
observed by the ALICE and STAR collaborations in peripheral hadronic A+ A collisions. This …

Highly charged relativistic heavy ions have high cross sections for two-photon interactions.
The photon flux is high enough that two-photon interactions may be accompanied by …
