  1. 45. Direct photon production and correlations at low $p_{\rm{T}}$ in Pb--Pb collisions with ALICE

    4. Electromagnetic and electroweak probes
    Oral presentation

    Measurements of direct photons can provide valuable information on the properties and evolution of the quark-gluon plasma (QGP); from the initial conditions to the pre-equilibrium, QGP, and the hadronic phase. In the ALICE experiment, photons that convert in the detector material are reconstructed down to low momentum using the excellent tracking capabilities. Furthermore, photons are...

  2. 240. Measurements of direct photons and dileptons at PHENIX

    4. Electromagnetic and electroweak probes
    Oral presentation

    Photons, both real and virtual, are one of the cleanest probes of high-density partonic matter produced in relativistic heavy-ion collisions as they carry unmodified information about the evolution of the system.
    Leveraging the versatility of RHIC, PHENIX has measured low momentum direct photons across different collision systems ranging from $p$+$p$ to Au+Au. An excess of direct photons,...

  3. 90. Thermal dielectron measurements in Au+Au collisions at BES-II energies with the STAR experiment

    4. Electromagnetic and electroweak probes
    Oral presentation

    Dielectrons, emitted during the evolution of the hot and dense QCD medium created in relativistic heavy-ion collisions, offer an effective probe of the hot medium properties, as they do not involve strong interactions. The dielectron emission rate is proportional to the medium's electromagnetic spectral function. In the dielectron mass range from $400$ to $800$ MeV/$c^{2}$, the spectral...

  4. 131. Measurements of thermal dielectron and QGP temperature in isobar collisions at $\sqrt{s_{\rm NN}}$ = 200 GeV

    4. Electromagnetic and electroweak probes
    Oral presentation

    Lattice QCD predicts a phase transition from hadronic matter to the Quark-Gluon Plasma (QGP) at high temperature and small baryon chemical potential. Thermal dileptons can be produced throughout the entire evolution of a collision and do not involve strong interactions. As a result, they can carry information about their emission source, and are therefore suggested as the ideal probes of hot...

  5. 46. Direct photon measurement in small systems and thermal radiation from QGP with ALICE
    Jerome Jung (Goethe University Frankfurt (DE))

    4. Electromagnetic and electroweak probes
    Oral presentation

    Electromagnetic probes are a unique tool for studying the space-time evolution of the hot and dense matter created in ultra-relativistic heavy-ion collisions. Dielectron pairs are emitted during the entire evolution of the medium created in such collisions, allowing the extraction of the real direct photon fraction at vanishing mass, providing access to thermal radiation from the early hot...
