  1. 533. Dilepton production in p+p, Au+Au collisions at $\sqrt{s_{NN}}$=200 GeV and U+U collisions at $\sqrt{s_{NN}}$=193 GeV

    Dileptons ($l^{+}l^{-}$) are produced throughout all stages of heavy-ion collisions and escape with minimum interaction with the strongly interacting medium. For this reason, $l^{+}l^{-}$ pair measurements play an essential role in the study of the hot and dense nuclear matter created in heavy-ion collisions. Dileptons in the low invariant mass region (up to M$_{ll}\sim$1~GeV/c$^2$) retain...

    We present a first measurement of low-mass electron pairs for a heavy collision-system at SIS18/Bevalac energies. The data is analyzed in terms of excess radiation above a conventional cocktail of contributions from meson decay after thermal freeze-out. We observe a strong excess radiation which is remarkably well described assuming emission from a thermalized system. The high statistics data...

  3. 517. Measurements of the dielectron continuum in pp, p-Pb and Pb-Pb collisions with ALICE at the LHC

    Oral

    Dielectrons produced in ultra-relativistic heavy-ion collisions at the LHC provide a unique probe of the whole system evolution as they are unperturbed by final-state interactions. The dielectron continuum is extremely rich in physics sources: on top of ordinary Dalitz and resonance decays of pseudoscalar and vector mesons, thermal black-body radiation is of particular interest as it carries...

  4. 282. Neutral particle-hadron correlation measurements with the ALICE experiment at the LHC

    Oral

    Among the probes used to investigate the properties of the Quark-Gluon Plasma, the measurement of the energy loss of high energy partons can be used to put constraints on energy loss models and to ultimately access medium characteristics (such as energy density or temperature). The study of two particle correlations allows to obtain very different constraints compared to the nuclear...

  5. 447. Bulk viscous effects on flow and dilepton radiation in a hybrid approach

    Oral

    Bulk viscosity has recently been shown to play an important role in describing both photon [1] and hadron [2] observables at the Relativistic Heavy-Ion Cllider (RHIC) and the Large Hadron Collider (LHC). The presence of a temperature-dependent bulk viscosity in the hydrodynamical evolution of the medium modifies the development of the hydronynamic momentum anisotropy differently in the high-...
