Title: 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{sup +}e{sup {minus}}) 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.
