abstract
We present the first theoretical study of the polarization of lepton pairs produced in $\sqrt{s_\mathrm{NN}} = 5.02$ TeV Pb+Pb collisions at the LHC, using next-to-leading order (NLO) dilepton emission rates. These calculations employ a multi-stage framework to simulate the evolution of relativistic heavy-ion collisions, and to explore the sensitivity of polarization to early times. It is found that the intermediate invariant-mass dileptons are indeed probes of the thermal equilibration process, and go beyond the reach of hadronic observables. We compute the polarization anisotropy coefficient obtained with LO dilepton rates, and show that the LO and NLO results differ radically, both in trend and in magnitude, at low and intermediate lepton pair invariant masses.

Thermal Dilepton Polarization under Rotation or Magnetic Field in Heavy-ion Collisions
Vorticity and magnetic fields induce characteristically different dilepton polarization spectra via modified quark propagators, with λ_θ decreasing monotonically under rotation but oscillating under magnetic fields du...

Spin alignment of Quarkonia: A Possible Probe of Deconfined QCD matter in Pb+Pb Collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV
Quarkonium spin alignment in heavy-ion collisions is predicted to increase with medium vorticity, but the model conflicts with current ALICE data at low transverse momentum.

Thermal dilepton production within conformal viscous Gubser flow
Thermal dilepton yields and effective temperatures are computed for conformal viscous Gubser flow, showing larger yields for lower q (larger systems) and higher effective temperatures for smaller systems.
