Ultra-peripheral collisions of relativistic heavy ions
We report the first observation of exclusive ρ production in ultra-peripheral collisions at RHIC. The ρ are produced electromagnetically at large impact parameters where no hadronic interactions occur. The produced ρ have a small perpendicular momentum, consistent with production that is coherent on both the photon emitting and scattering nuclei. We observe both exclusive ρ production, and ρ pr...

متن کاملCalculation of Higher Order Effects in Electron-Positron Pair Production in Relativistic Heavy Ion Collisions
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 collisions. Also total cross sections are given for SPS and RHIC energies. We make use of the expression derived recently by several groups where the summation of all higher orders can be done analytically in the h...
متن کاملNonperturbative character of electron-positron pair production in relativistic heavy-ion collisions.
In recent years, a large number of papers have appeared that dealt with e+e− pair production in heavy ion collisions at high energies. To a large extent these studies were motivated by the existence of relativistic heavy ion accelerators all over the world. There pair production can be studied in so called “ultra-peripheral collisions”, where the ions do not come close enough to interact strong...
متن کاملElectron-positron pair production in the external electromagnetic field of colliding relativistic heavy ions
The results concerning the e+e− production in peripheral highly relativistic heavy-ion collisions presented in a recent paper by Baltz et al. are rederived in a very straightforward manner. It is shown that the solution of the Dirac equation directly leads to the multiplicity, i.e. to the total number of electronpositron pairs produced by the electromagnetic field of the ions, whereas the calcu...
