Dilepton Radiation at the CERN Super Proton Synchrotron

  title={Dilepton Radiation at the CERN Super Proton Synchrotron},
  author={Hendrik van Hees and Ralf Rapp},
A quantitative evaluation of dilepton sources in heavy-ion reactions is performed taking into account both thermal and non-thermal production mechanisms. The hadronic thermal emission rate is based on an electromagnetic current-correlation function with a low-mass region (LMR, M . 1 GeV) dominated by vector mesons (ρ, ω, φ) and an intermediate-mass region (IMR, 1 GeV ≤ M ≤ 3 GeV) characterized by (the onset of) a multi-meson continuum. A convolution of the emission rates over a thermal fireball… CONTINUE READING
