Dilepton production from p-p to Ca-Ca at the Bevalac
Abstract
The DLS collaboration has recently completed a high statistics study of dilepton production at the Bevalac. In particular, we have measured dielectrons e(+)e(-) from p-p and p-d collisions to understand the basic dilepton production mechanisms in the energy range from 1.05-4.9 GeV. These data can be used to determine the basic processes which contribute to nucleon-nucleon dilepton production such as hadronic bremsstrahlung, vector meson processes, and hadronic Dalitz decay. The data show that a simple elastic bremsstrahlung calculation is insufficient to explain the data. Theoretical models are compared with the data. A new high statistics study of Ca-Ca at 1.05 A(center dot)GeV has been made to study the collectivity of A-A collisions.
