We explore the possibility of measurements of Hanbury Brown–Twiss correlations in γ γ
channels in the high multiplicity environment of heavy ion collisions. We consider all …

Coulomb effects on π±and K±spectra in relativistic nuclear collisions are investigated. At
collision energies around 1 GeV the ratio of π− to π+ is enhanced several times at low …

The production of high-energy photons in an intermediate energy heavy-ion reaction (65
MeV/nucleon Ar+ Nb) is studied by characterizing the events, which produce the photons, by …

We present data on e+ e− pair production accompanied by nuclear breakup in
ultraperipheral gold-gold collisions at a center of mass energy of 200 GeV per nucleon pair …

The synchrotron photon spectrum in heavy ion collisions is computed taking into account the
spatial and temporal structure of the magnetic field. It is found that a significant fraction of …

We present a calculation of higher order effects for the impact-parameter-dependent
probability for single and multiple electron-positron pairs in (peripheral) relativistic heavy ion …

X-ray studies of relativistic heavy-ion-atom collisions allow the direct observation of the
radiative-electron-capture photons. The angular distribution of these photons is …

The PHENIX collaboration presents first measurements of low-momentum (0.4< p T< 3
GeV/c) direct-photon yields from Au+ Au collisions at s NN= 39 and 62.4 GeV. For both …

We consider a two-step process that may occur in relativistic ion-atom collisions. In this
process, within a single ion-atom collision, an atomic electron is captured by the ion via the …

We have analyzed hard-photon intensity correlations measured in the systems 86Kr+ natNi
at 60.0 A MeV and 181Ta+ 197Au at 39.5 A MeV assuming that hard photons are emitted …
