Photons from Pb-Pb collisions at ultrarelativistic energies
High energy photon emission rate from matter created in Pb+Pb collisions at CERN SPS energies is evaluated. The evolution of matter from the initial state up to freeze-out has been treated within the framework of (3+1) dimensional hydrodynamic expansion. We observe that the photon spectra measured b...
