In this work we have calculated the total cross sections of electron-positron pair production for the collisions of fully stripped gold ions for various energies. We have also compared our calculation with other methods.

Publisher and Date:(Institute of Physics Publishing, 2011)In peripheral collisions the strong electromagnetic fields are produced since the fully stripped heavy ions moves at ultra-relativistic velocities. Lepton pairs especially the electron-positron pairs are the result of this collisions. At the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC) virtual photons produce many particles such as electron-positron pairs heavy lepton (muons and tauons) pairs magnetic monopoles W-pairs b-quark pairs and possibly the Higgs. At small ...
The STAR Collaboration at the Relativistic Heavy Ion Collider present data on electron-positron pair production accompanied by nuclear breakup at small impact parameters where the simultaneous excitation of the two ions mainly the giant dipole resonance GDR can occur. We calculate the electron-positron pair production cross section relevant for the STAR experimental setup and compare our results with the other calculations. © 2007 Elsevier B.V. All rights reserved.
