Thermal Dileptons in High-Energy Heavy-Ion Collisions

(Research group of Ralf Rapp at Texas A&M University)


On this site you will find data files for theoretically calculated in-medium rho spectral functions (SFs) from hadronic many-body theory, and thermal dilepton spectra from Quark-Gluon Plasma and Hadronic Matter in various nuclear collision systems. If you intend to utilize these data files for your research, please contact Dr. Rapp and cite the pertinent original papers as quoted in the file headers.


        Rho-Meson Spectral Functions    
  • SIS-18 / HADES regime: in-medium rho SF along isentropic trajectories here.
  • RHIC/LHC regime: in-medium rho, omega and phi SFs along isentropic trajectory here.
