    4. Electromagnetic and electroweak probes
    Oral presentation

    The idea of using dilepton measurements to construct a phenomenology of the early pre-equilibrium phase of heavy-ion collisions has been recently posed [1,2]. Nevertheless, a full computation of pre-equilibrium radiation yields was still missing. In this work, we use QCD kinetic theory to compute dilepton production coming from the pre equilibrium phase of the Quark-Gluon Plasma created in...

    4. Electromagnetic and electroweak probes
    Oral presentation

    Dilepton radiation is known to be an effective thermometer of the quark-gluon plasma (QGP) [1]. In this study, we explore the possibility of using dilepton radiations as a QGP magnetometer. We calculate corrections to dilepton production rate at finite baryon chemical potential, in the presence of a time-dependent magnetic field typically found in heavy-ion collisions. At first order, such a...

  3. 185. Dilepton emission in heavy ion collisions and chemical equilibrium of QCD matter

    4. Electromagnetic and electroweak probes
    Oral presentation

    Dileptons are produced throughout the entire evolution history of the medium. Owing to their electromagnetic coupling to strongly interacting matter, dileptons traverse the QGP medium unaltered after their production and carry information about their space-time points of production. The emissivity is correlated with the quark abundance in the collision system as well. Therefore, dileptons...
