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...

description 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.
