Electromagnetic probes in ALICE at the LHC

Daiki Sekihata (University of Tokyo)

Electromagnetic probes such as photons and dielectrons ($\mathrm{e}^{+}\mathrm{e}^{-}$ pairs) are a unique tool to study the space-time evolution of the hot and dense matter created in ultra-relativistic heavy-ion collisions. They are produced at all stages of the collision with negligible final-state interactions.

In this talk, latest measurements of the dielectron and direct-photon production in ALICE will be presented and compared to model calculations. Finally, first results in pp collisions at $\sqrt{s} = 13.6 \, \mathrm{TeV}$ with the upgraded ALICE detector in Run 3 will be reported.
