  1. 287. Measurements of dielectron production in Au+Au collisions at $\sqrt{s_{\text{NN}}}$ = 27, 54.4 and 200 GeV with the STAR experiment

    Oral Presentation

    Dielectrons are suggested as excellent probes of the hot and dense medium created in relativistic heavy-ion collisions due to their minimal interactions with the partonic and hadronic medium. They can carry the information from the initial to the final stage of a collision. The study of the dielectron mass spectrum could help to disentangle various contributions. In the low mass region (LMR,...

  2. 191. Low-mass dielectron measurements in pp, p-Pb and Pb-Pb collisions with ALICE at the LHC

    Oral Presentation

    The production of low-mass dielectrons is the most promising tool for the understanding of the chiral symmetry restoration and of the properties of the Quark-Gluon Plasma (QGP)
    created in heavy-ion collisions. At low invariant mass, the dielectron production is sensitive to the properties of vector mesons in the medium related to the chiral symmetry
    restoration. In the intermediate-mass...

  3. 182. Signatures of chiral symmetry restoration in dilepton production

    Oral Presentation

    We study the structural change of the vector spectral function and integrated production rates
    of dileptons in the presence of the chiral mixing induced exclusively at finite density. The mixing
    produces multiple bumps and peaks around the vacuum masses of the rho, omega and phi resonances in the spectral function. The arising modifi?cation becomes pronounced when the mass difference between...

  4. 348. Electromagnetic radiation from the pre-equilibrium/pre-hydro stage of the quark-gluon plasma

    Oral Presentation

    A remarkable achievement of the relativistic heavy-ion program is the realization that relativistic fluid dynamics can describe the evolving system of quark-gluon plasma (QGP) from its early moments to a time when the growing mean-free-paths drive the system out of equilibrium. The effectiveness of this hydrodynamic description is judged by comparing calculated hadronic observables with...

  5. 623. Thermal photon production in Au+Au collisions from PHENIX
    Wenqing Fan (Stony Brook University)

    Electromagnetic probes
    Oral Presentation

    PHENIX measurements of low $p_T$ direct photons in Au+Au collisions at 200 GeV show large yields and simultaneously large anisotropies with respect to the reaction plane. Calculations of thermal photon emission fall short in describing the yield and the anisotropy at the same time. Furthermore, a recent publication of the STAR collaboration indicates lower direct photon yields in Au+Au...
