Soft Dilepton Production in Au-Au Collisions by Twophoton Processes

Abstract
The production of the low transverse momentum (PT) dileptons induced by semicohe rent twophoton interaction is calculated. The numerical results are compared with the experimental data from the PHENIX, the modification of the semicoherent twophoton interaction is remarkable in the low transverse momentum region for different mass bins. We find that the contribution of semicoherent twophoton processes is more evident in the large dilepton mass region.
