Spectral redshift versus broadening from photon and dilepton spectra
We estimate the photon and dilepton emission rates from hot hadronic matter with in-medium spectral shift and broadening of vector mesons. It is observed that both the WA98 photon data and CERES/NA45 dilepton data can be well reproduced with similar initial conditions. We argue that simultaneous mea...

| Sumario: | We estimate the photon and dilepton emission rates from hot hadronic matter with in-medium spectral shift and broadening of vector mesons. It is observed that both the WA98 photon data and CERES/NA45 dilepton data can be well reproduced with similar initial conditions. We argue that simultaneous measurement of the $p_{T}$ spectra of single photons and invariant mass distribution of dileptons is important to understand the in-medium spectral function of the vector mesons. |
