The production of dileptons with an invariant mass in the range 1 GeV < M < 5 GeV provides unique insight into the approach to thermal equilibrium in ultrarelativistic nucleus-nucleus collisions. In this mass range, they are produced through the annihilation of quark-antiquark pairs in the early stages of the collision. They are sensitive to the anisotropy of the quark momentum distribution, and also to the quark abundance, which is expected to be underpopulated relative to thermal equilibrium. We take into account both effects based on recent theoretical developments in QCD kinetic theory, and study how the dilepton mass spectrum depends on the shear viscosity to entropy ratio that controls the equilibration time. We evaluate the background from the Drell-Yan process and argue that future detector developments can suppress the additional background from semileptonic decays of heavy flavors.

Thermal dilepton polarization and dynamics of the QCD plasma in relativistic heavy-ion collisions
Using next-to-leading-order rates, the paper predicts that dilepton polarization changes sign and magnitude in low and intermediate invariant-mass ranges, making it a sensitive probe of gluonic processes and pre-equil...

Effective temperatures of the QGP from thermal photon and dilepton production
In the Trajectum model, dilepton effective temperatures reliably track the quark-gluon plasma temperature, while photon effective temperatures are biased by flow and stay near 250-300 MeV.

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.
