Photons and lepton pairs are close to the ideal probes to study the dynamics of the dense system of strongly interacting quanta expected to be produced in ultrarelativistic nucleus-nucleus collisions1,2. Electromagnetic interactions are strong enough to lead to a detectable signal from the secondary collisions of final state particles, yet, they are weak enough to let the emitted photons and leptons to escape from the finite nuclear system without further interactions. Thus, the spectra of photons and dileptons from the dense phase of the collision can provide information on the properties of the constituents and on their momentum distributions.
